Abstract
Functionalized 2-pyridones are important biologically active compounds, DNA base analogues and synthetic intermediates. Herein, we report a simple, green, solid-state synthesis of differently substituted 2-pyridones. It starts from commercially available amines and activated alkynes, uses silica gel (15%Cs2CO3/SiO2) as the solid phase and a reaction vial as the only equipment. If necessary, heating is performed in a laboratory oven. Since most reactions are completed within a few hours, no additional energy consumption is required. The syntheses do not require solvents and other reagents and are easily monitored by standard analytical techniques. The atom economy is high, since all atoms of reactants are present in the products and EtOH is the only by-product. The syntheses produce polyfunctionalized conjugated dienes as the only intermediates, which are also important building blocks.

Chemistry 2023; 29:e202302335. [PMID: 37555389 DOI: 10.1002/chem.202302335] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 08/05/2023] [Accepted: 08/09/2023] [Indexed: 08/10/2023]
Abstract
The geometrical regioselective E→Z isomerization of a conjugated alkene under thermal activation pose a challenge due to microscopic reversibility. Herein we report that such reversibility issues can be circumvented by integrating E→Z isomerization with subsequent cyclization cascade, particularly in the absence of commonly employed light, acids, or metal-catalysts. Thus, linearly conjugated dienals in a mixture of toluene-alcohol (2 : 1) solvents or only with alcohol at 60-70 °C can be converted to γ-alkoxybutenolides in moderate to good yields. The intermediary 2Z,4E-isomer can be isolated, which includes the first example of isolating the regioselective isomerization product under thermal conditions. Density functional theory (DFT) studies have been employed to shed light on the feasibility of geometrical alkene isomerization and ensuing cascade sequences. It has been observed that the regioselective 2E,4E→2Z,4E isomerization of dienal is a thermodynamically facile (ΔG <0) process. Structural elucidation further reveals that the presence of a certain charge transfer and a non-covalent interaction may be the primary reasons for the enhanced stability of the 2Z,4E-isomer. The thermodynamic plausibility of the subsequent cascade reaction from the Z-isomer to the anticipated product in the presence of a polar protic solvent (here MeOH) is also explicated. Out of the two probable pathways, the "hemiacetal pathway" involving a relay proton transfer is kinetically more feasible due to the diminished activation barrier than the "conjugate addition pathway".

Abstract
In the quest to develop potent inhibitors for Mycobacterium tuberculosis, novel isoniazid-based pyridinium salts were designed, synthesized, and tested for their antimycobacterial activities against the H37 Rv strain of Mycobacterium tuberculosis using rifampicin as a standard. The pyridinium salts 4k, 4l, and 7d showed exceptional antimycobacterial activities with MIC90 at 1 µg/mL. The in vitro cytotoxicity and pharmacokinetics profiles of these compounds were established for the identification of a lead molecule using in vivo efficacy proof-of-concept studies and found that the lead compound 4k possesses LC50 value at 25 µg/mL. The in vitro antimycobacterial activity results were further supported by in silico studies with good binding affinities ranging from -9.8 to -11.6 kcal/mol for 4k, 4l, and 7d with the target oxidoreductase DprE1 enzyme. These results demonstrate that pyridinium salts derived from isoniazid can be a potentially promising pharmacophore for the development of novel antitubercular candidates.

Abstract
AbstractPhenotype-guided transposon mutagenesis has emerged as a valuable tool to access cryptic metabolites encoded in bacterial genomes. Recently, the method was demonstrated by inducing silent biosynthetic gene clusters in Burkholderia thailandensis. Amongst the isolated metabolic products, thailandene A exhibited promising antibiotic activity. By assignment, the linear polyenic aldehyde contained a labile motif, where an ostensible chiral secondary alcohol was interlaced in an allylic and a homoallylic constellation. Our attention was drawn to the pseudo-symmetric relationship between the heterofunctionalities, indicating the transformation of a dodecapentaenedial scaffold. Centering on an iterative cross-coupling protocol, the assigned all-E-(12R)-hydroxydodecapentaenal moiety was assembled by combining Zincke chemistry with the MIDA-attenuated Suzuki reaction developed in the Burke laboratory. Thus, according to the devised strategy, the mixed 1,2-bisborylated vinyl linchpin was consecutively functionalized with 5-bromodienal derivatives in a doubly orthogonal fashion. However, when the synthetic material was matched against the bacterial isolate, inconsistencies were observed. A re-examination of the cryptic natural product was conducted by juxtaposing analytical data from experiment and density functional theory calculations, in which hydroperoxide was evaluated as a candidate metabolite present in the bacterial isolate.

Abstract
The formation of C-aryl bonds has been the focus of intensive research over the last decades for the construction of complex molecules from simple, readily available feedstocks. Traditionally, these strategies involve the coupling of organohalides (I, Br, Cl) with organometallic reagents (Mg, Zn, B, Si, Sn,…) such as Kumada-Corriu, Negishi, Suzuki-Miyaura, Hiyama and Sonogashira cross-couplings. More recently, alternative methods have provided access to these products by reactions with less reactive C-Het (F, O, S, N) and C-C bonds. Compared to traditional methods, the direct cleavage and arylation of these chemical bonds, the essential link in accessible feedstocks, has become increasingly important from the viewpoint of step-economy and functional-group compatibility. This comprehensive review aims to outline the development and advances of this topic, which was organized into (1) C-F bond arylation, (2) C-O bond arylation, (3) C-S bond arylation, (4) C-N bond arylation, and (5) C-C bond arylation. Substantial attention has been paid to the strategies and mechanistic investigations. We hope that this review can trigger chemists to discover more efficient methodologies to access arylation products by cleavage of these C-Het and C-C bonds.

Abstract
The resolution of inflammation is a biosynthetically active process controlled by the interplay between oxygenated polyunsaturated mediators and G-protein coupled receptor-signaling pathways. These enzymatically oxygenated polyunsaturated fatty acids belong to distinct families of specialized pro-resolving autacoids. The protectin family of mediators has attracted an interest because of their potent pro-resolving and anti-inflammatory actions verified in several in vivo disease models. Herein, we present the stereoselective synthesis and biological evaluations of 3-oxa-PD1n-3 DPA, a protectin D1 analog. Results from mouse models indicate that the mediators protectin D1, PD1n-3 DPA and the new analog 3-oxa-PD1n-3 DPA all relieved streptozotocin-induced diabetic neuropathic pain at doses of 90 and 300 pmol, equivalent to 30 and 100 ng, respectively, following intrathecal (I.T.) injection. Of interest, at a low dose of only 30 pmol (10 ng; I.T.) only 3-oxa PD1n-3 DPA was able to alleviate neuropathic pain, directly compared to vehicle controls. Moreover, using a chronic itch model of cutaneous T-cell lymphoma (CTCL), all three compounds at 300 pmol (100 ng) showed a significant reduction in itching for several hours. The biomolecular information on the structure-functions of the protectins and the new synthetic analog 3-oxa-PD1n-3 DPA is of interest towards developing new immunoresolvents.

Abstract
Recent research efforts focusing on the many mechanisms participating in the resolution of acute inflammation have uncovered a new genus of pro-resolving lipid mediators. These endogenous molecules include the lipoxins, resolvins, protectins and maresins, collectively coined specialized pro-resolving mediators (SPMs). SPMs are oxygenated polyunsaturated fatty acids biosynthesized by lipoxygenases and cyclooxygenases enzymes. These chemically sensitive molecules are produced in nano- to pico-gram amounts in vivo and exhibit potent anti-inflammatory and pro-resolving bioactions. In addition, SPMs clear bacterial infections, reduce pain and display bioactivities towards host defense, organ protection and tissue remodeling. Altogether, these bioactions and the need for synthetic SPMs for determination of absolute configuration and in vivo experiments have spurred a great interest in the synthetic and biomolecular communities. This review covers reported stereoselective total syntheses and outlines the most significant bioactions of the E-series resolvins.

Abstract
A stereodivergent strategy has been devised to access the diene motif found in biologically active compounds from the Piperaceae family. Herein the first total syntheses of 2E,4E configured piperchabamide E (2) and its enantiomer (ent-2), as well as 2E,4Z configured scutifoliamide B (3), are narrated. The mainstay in the adopted approach is the gram-scale conversion of quaternized pyridine in a practical three-step sequence to access isomerically pure conjugated bromodiene esters 2E,4E8 and 2E,4Z9 by differential crystallization. Even though the developed oxidation protocol forms the basis of the entailed divergent strategy, the geometrical integrity of the involved bromodiene motive can be controlled by the choice of solvent. Thus, while oxidation of pure bromodienal 2E,4Z7 in methanol yields equal amounts of bromodiene esters 2E,4E8 and 2E,4Z9, only bromodiene ester 2E,4Z10 is formed in isopropanol. Subseqently, capitalizing on a stereoretentive Suzuki cross-coupling and direct amidation of the corresponding esters, the featured natural products can be accessed in five and six steps, respectively. The somewhat surprising (R)-configured amine portion, which has been assigned to piperchabamide E (2), is facilitated by a Curtius rearrangement. Following this, the actual amine portion is shown to be (S)-configured.

Abstract
N-Alkylation significantly changes the electronic and optical properties, as well as the reactivity of nitrogen-containing π-conjugated molecules. In this study, it is found that treating 5,15-diazaporphyrins with methyl triflate selectively affords the corresponding N-methyl-5,15-diazaporphyrinium cations in good yield. N-Methylation substantially alters the electronic properties and reactivity of diazaporphyrins. The electron-accepting properties of the N-methyl-5,15-diazaporphyrinium cations are enhanced due to their lowered LUMO level. Stabilization of the LUMO energy enables regio- and stereoselective Diels-Alder reactions of the cationic diazaporphyrin with cyclopentadiene. N-Methylation also enhances the acidity of the inner NH protons, and thus, allows facile deprotonation to provide nitrogen-substituted isoporphyrin analogues with only one NH group in the central cavity.

Abstract
Katritzky salts are used as the alkyl radical precursors with the insertion of sulfur dioxide under photoredox catalysis. This transformation first enables direct generation of various alkylsulfonyl radicals by photoinduced single electron reduction, leading to diverse dialkyl sulfones in good to excellent yields. A radical pathway is proposed under visible-light induced conditions with the insertion of sulfur dioxide.

Abstract
PD1n-3 DPA belongs to the protectin family of specialized pro-resolving lipid mediators. The protectins are endogenously formed mediators that display potent anti-inflammatory properties and pro-resolving bioactivities and have attracted interest in drug discovery. However, few studies have been reported of the secondary metabolism of the protectins. To investigate the metabolic formation of the putative C22 mono-hydroxylated product, coined 22-OH-PD1n-3 DPA, a stereoselective synthesis was performed. LC/MS-MS data of synthetic 22-OH-PD1n-3 DPA matched the data for the biosynthetic formed product. Cellular studies revealed that 22-OH-PD1n-3 DPA is formed from n-3 docosapentaenoic acid in human serum, and we confirmed that 22-OH-PD1n-3 DPA is a secondary metabolite produced by ω-oxidation of PD1n-3 DPA in human neutrophils and in human monocytes. The results reported are of interest for enabling future structure–activity relationship studies and provide useful molecular insight of the metabolism of the protectin class of specialized pro-resolving mediators.

Abstract
Protectin D1 is a specialized pro-resolving mediator with potent pro-resolving and anti-inflammatory effects in vivo in several human disease models. Herein the preparation of the first synthetic analog of protectin D1, named 22-F-PD1, is presented together with data from in vivo investigations. This analog showed potent pro-resolving and anti-inflammatory properties. These results inspired the preparation of the radiotracer 22-[18F]F-PD1-ME that was used in a positron emission tomography proof of concept study. Altogether, the findings presented contribute to new knowledge on the biomolecular properties of protectin D1 analogs. In addition, an improved formal synthesis of the metabolite 22-OH-PD1 is reported.

Abstract
We present an efficient, simple, metal- and solvent-free silica-gel-promoted synthesis of functionalized conjugated dienes by sequential aza-Michael/Michael reactions by starting from commercially available primary amines and propiolic esters. The scope and usefulness of the method is demonstrated for 31 examples, including a range of propiolic esters, aliphatic amines, and differently substituted aromatic amines. For aliphatic amines, the products were obtained within 0.5 to 4 h in 52 to 85 % yield, compared with 3.5 to 22 h under classical solution-phase synthesis, which proceeds with similar or lower yields. The method was found to be particularly useful for weakly nucleophilic aromatic amines, which provided products in 21 to 73 % yield over 2.5 to 9.5 h compared with yields of 0 to 49 % over 1 to 6 d under standard solution-phase conditions, and for more hydrophobic esters that gave products in yields of 47 to 79 % over 1 to 3 h compared with 0 to 45 % over 4 to 114 h in solvent.

Abstract
Driven by a new biogenetic hypothesis, the first total synthesis of alsmaphorazine B and several related indole alkaloids has been achieved. Numerous early approaches proved unsuccessful owing to unproductive side reactivity; nevertheless, they provided important clues that guided the evolution of our strategy. Critical to our success was a major improvement in our Zincke aldehyde cycloaddition strategy, which permitted the efficient gram-scale synthesis of akuammicine. The sequential chemoselective oxidations of akuammicine leading up to the key oxidative rearrangement also yielded several biogenetically related indole alkaloids en route to alsmaphorazine B.

Abstract
Several novel oxygenated polyunsaturated lipid mediators biosynthesized from n-3 docosapentaenoic acid were recently isolated from murine inflammatory exudates and human primary cells. These compounds belong to a distinct family of specialized pro-resolving mediators, and display potent in vivo anti-inflammatory and pro-resolution effects. The endogenously formed specialized pro-resolving mediators have attracted a great interest as lead compounds in drug discovery programs towards the development of new classes of drugs that dampen inflammation without interfering with the immune response. Detailed information on the chemical structures, cellular functions and distinct biosynthetic pathways of specialized pro-resolving lipid mediators is a central aspect of these biological actions. Herein, the isolation, structural elucidation, biosynthetic pathways, total synthesis and bioactions of the n-3 docosapentaenoic acid derived mediators PD1n-3 DPA and MaR1n-3 DPA are discussed. In addition, a brief discussion of a novel family of mediators derived from n-3 docosapentaenoic acid, termed 13-series resolvins is included.
