Nat Commun 2018; 9:4251. [PMID: 30315170 PMCID: PMC6185983 DOI: 10.1038/s41467-018-06766-1] [Citation(s) in RCA: 65] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 09/24/2018] [Indexed: 11/24/2022] Open
Abstract
Iridium N-heterocyclic carbene (NHC) complexes catalyse the para-hydrogen-induced hyperpolarization process, Signal Amplification by Reversible Exchange (SABRE). This process transfers the latent magnetism of para-hydrogen into a substrate, without changing its chemical identity, to dramatically improve its nuclear magnetic resonance (NMR) detectability. By synthesizing and examining over 30 NHC containing complexes, here we rationalize the key characteristics of efficient SABRE catalysis prior to using appropriate catalyst-substrate combinations to quantify the substrate's NMR detectability. These optimizations deliver polarizations of 63% for 1H nuclei in methyl 4,6-d2-nicotinate, 25% for 13C nuclei in a 13C2-diphenylpyridazine and 43% for the 15N nucleus of pyridine-15N. These high detectability levels compare favourably with the 0.0005% 1H value harnessed by a routine 1.5 T clinical MRI system. As signal strength scales with the square of the number of observations, these low cost innovations offer remarkable improvements in detectability threshold that offer routes to significantly reduce measurement time.

Abstract
A mild and practical Barbier-Negishi coupling of secondary alkyl bromides with aryl and alkenyl triflates and nonaflates has been developed. This challenging reaction was enabled by the use of a very bulky imidazole-based phosphine ligand, which resulted in good yields as well as good chemo- and site selectivities for a broad range of substrates at room temperature and under non-aqueous conditions. This reaction was extended to primary alkyl bromides by using an analogous pyrazole-based ligand.

Abstract
Over the past decade, the use of Pd-NHC complexes in cross-coupling applications has blossomed, and reactions that were either not previously possible or possible only under very forcing conditions (e.g., > 100 °C, strong base) are now feasible under mild conditions (e.g., room temperature, weak base). Access to tools such as computational chemistry has facilitated a much greater mechanistic understanding of catalytic cycles, which has enabled the design of new NHC ligands and accelerated advances in cross-coupling. With these elements of rational design, highly reactive Pd-NHC complexes have been invented to catalyze the selective formation of single products in a variety of transformations that have the potential to afford multiple compounds (e.g., isomers). Pd-NHC catalysts may be prepared as stable Pd(II) precatalysts that are readily reduced to the active Pd(0) species in the presence of an organometallic cross-coupling partner or nucleophile possessing β-hydrogens. It has been found from computational and experimental results that Pd-NHC complexes bearing a single bulky NHC ligand are well-suited to tackle challenging cross-coupling reactions. N-Aryl-substituted imidazole-2-ylidenes with branched alkyl chains at the ortho positions of the aryl group are effective for the challenging couplings of hindered biaryls, secondary alkyl organozincs, electron-deficient anilines, α-amino esters, primary alkylamines, and ammonia. The bulk of the NHC has been tuned by increasing the size of the alkyl groups at the ortho positions and substituting the NHC core with chlorine substituents. All of the cross-coupling transformations studied benefit from the increased bulk when the ortho groups are changed from methyl to 2-propyl to 3-pentyl. However, there is a limit to the positive effect of steric bulk, as some reactions do not benefit from the increased size of the 4-heptyl group compared with 3-pentyl. Thus, there is an optimum size for the NHC ligand that depends upon whether reactivity (turnover frequency and turnover number), selectivity, or both are needed to obtain the desired reaction outcome. In the cases that we have studied, reactivity and selectivity increase together (i.e., the fastest catalyst is also the most selective), allowing cross-couplings to be carried out under mild conditions to obtain one product with high selectivity. This Account focuses on seminal literature reports that have disclosed new Pd-NHC complexes that have led to significant breakthroughs in efficacy for challenging couplings while demonstrating high selectivity for the desired target. These catalysts have been used widely in materials science, pharmaceutical, and agrochemical applications.

Abstract
Disclosed herein is the first general chemo- and site-selective alkylation of C-Br bonds in the presence of COTf, C-Cl and other potentially reactive functional groups, using the air-, moisture-, and thermally stable dinuclear PdI catalyst, [Pd(μ-I)PtBu3 ]2 . The bromo-selectivity is independent of the substrate and the relative positioning of the competing reaction sites, and as such fully predictable. Primary and secondary alkyl chains were introduced with extremely high speed (<5 min reaction time) at room temperature and under open-flask reaction conditions.

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.

Abstract
Transition metal-catalysed cross-coupling is one of the most powerful synthetic methods and has led to vast improvements in the synthesis of pharmaceuticals, agrochemicals and precursors for materials chemistry. A major advance in cross-coupling over the past 20 years is the utilization of well-defined, bench-stable Pd and Ni precatalysts that do not require the addition of free ancillary ligand, which can hinder catalysis by occupying open coordination sites on the metal. The development of precatalysts has resulted in new reactions and expanded substrate scopes, enabling transformations under milder conditions and with lower catalyst loadings. This Review highlights recent advances in the development of Pd and Ni precatalysts for cross-coupling, and provides a critical comparison between the state of the art in Pd- and Ni-based systems.

Abstract
A Pd-catalyzed/N-heterocycle-directed C(sp(3) )-H olefination has been developed. The monoprotected amino acid ligand (MPAA) is found to significantly promote Pd-catalyzed C(sp(3) )-H olefination for the first time. Cu(OAc)2 instead of Ag(+) salts are used as the terminal oxidant. This reaction provides a useful method for the synthesis of alkylated pyrazoles.

Abstract
The first enantioconvergent palladium-catalyzed Fukuyama cross-coupling of racemic benzylic organozinc reagents with thioesters has been developed. The reaction furnishes enantioenriched acyclic α-disubstituted ketone products in good yields and high enantioselectivities. A broad substrate scope is achieved under mild reaction conditions to prevent racemization of the potentially labile tertiary stereocenters.

Abstract
An atom-economic synthetic route to benzimidazolium salts is presented. The annulated polycyclic systems: 1,3-bis(2,4,6-trimethylphenyl)-1H-benzo[d]imidazol-3-ium chloride (1-Cl), 1,3-bis(2,6-diisopropylphenyl)-1H-benzo[d]imidazol-3-ium chloride (2-Cl), 1,3-diphenyl-1H-benzo[d]imidazol-3-ium chloride (3-Cl), and 1,3-di(pyridin-2-yl)-1H-benzo[d]imidazol-3-ium chloride (4-Cl) were prepared in a two-step synthesis avoiding chromatographic work-up. In the key step triethyl orthoformate is reacted with the corresponding N1,N2-diarylbenzene-1,2-diamines and then further transformed in situ, by alkoxy abstraction using trimethylsilyl chloride (TMSCl), and concomitant imidazole ring closure.

Abstract
Current state-of-the-art protocols for the coupling of unreactive amines (e.g., electron-poor anilines) with deactivated oxidative-addition partners (e.g., electron-rich and/or hindered aryl chlorides) involve strong heating (usually >100°C) and/or tert-butoxide base, and even then not all couplings are successful. The aggressive base tert-butoxide reacts with and in many instances destroys the typical functional groups that are necessary for the function of most organic molecules, such as carbonyl groups, esters, nitriles, amides, alcohols, and amines. The new catalyst described herein, Pd-PEPPSI-IPentCl-o-picoline, is able to aminate profoundly deactivated coupling partners when using only carbonate base at room temperature.

Abstract
The cross-coupling of aryl tosylates with amines and anilines was achieved by using for the first time a Pd-NHC system based on the popular Pd-PEPPSI precatalyst platform in which the anchoring imidazol-2-ylidene ligand IPr((NMe2)2) incorporates two dimethylamino groups as backbone substituents enhancing both the electronic and steric properties of the carbene. The system optimization and its application scope are disclosed.
