CHEMSUSCHEM 2024; 17:e202301882. [PMID: 38242851 DOI: 10.1002/cssc.202301882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 01/14/2024] [Accepted: 01/19/2024] [Indexed: 01/21/2024]
Abstract
A novel and efficient approach for the synthesis of α, β-unsaturated sulfones through heterogeneous photocatalyzed C-S coupling reactions have been developed. The use of molten-salt method derived carbon nitride (MCN), a transition metal-free polymeric photocatalyst, combined with enhanced crystallinity and potassium iodide as an additive, effectively modulates photogenerated reactive redox species, markedly increasing the overall reaction selectivity. This method achieves the shortest reaction time (2 h) with high yield (up to 95 %) among the reported heterogeneous catalytic C-S bond formation reactions, matching the efficiency of the homogeneous photocatalysts. Furthermore, the application to challenging alkyne substrates has been demonstrated, underscoring the potential for a broad range of applications in pharmaceutical research and synthetic chemistry.

Abstract
In modern organic synthesis, the execution of reactions in the absence of expensive transition metals has received significant attention from the view-point of green chemistry and sustainable development. As a consequence, the combination of MI-TBHP as an oxidation system (M = Na, K, NH4) has opened a new avenue with significant impact for the succinct synthesis of complex heterocycle molecules via the construction of various chemical bonds [C-X (X = C, N, S, O), N-X (X = N, P) and S-N]. This comprehensive review article delineates the progress of recent developments in this emerging area, with an in-depth discussion on the substrate scope, limitations and proper mechanistic underpinnings. We hope this review will highlight the great potential of this MI-TBHP as a powerful oxidation system and inspire researchers to conduct further endeavors in this domain.

Abstract
Reported herein are practical approaches for the chemoselective mono-, di-, and tri-iodination of alkynes based on efficient oxidative iodinations catalyzed by hypervalent iodine reagents. The reaction conditions were systematically optimized by altering the iodine source and/or the hypervalent iodine reagent system. The tetrabutylammonium iodide (TBAI)/(diacetoxyiodo)benzene (PIDA) system is specific for monoiodination, while the KI/PIDA system results in di-iodination. Combining the TBAI/PIDA and KI/PIDA systems in one pot provided the corresponding tri-iodination products efficiently. These reaction conditions can be applied to the synthetically important iodination of aromatic and aliphatic alkynes, which was accomplished in good yield (up to 99%) and excellent chemoselectivity. These synthetic methods can also be applied to the efficient chemoselective synthesis of iodoalkyne derivatives, intermediates, and related biologically active compounds.

Nucl Med Biol 2015; 42:673-84. [PMID: 25956997 PMCID: PMC4481138 DOI: 10.1016/j.nucmedbio.2015.04.005] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2014] [Revised: 04/10/2015] [Accepted: 04/13/2015] [Indexed: 01/15/2023]
Abstract
INTRODUCTION Radioiodinated meta-iodobenzylguanidine (MIBG), a norepinephrine transporter (NET) substrate, has been extensively used as an imaging agent to study the pathophysiology of the heart and for the diagnosis and treatment of neuroendocrine tumors. The goal of this study was to develop an (18)F-labeled analogue of MIBG that like MIBG itself could be synthesized in a single radiochemical step. Towards this end, we designed 4-fluoropropoxy-3-iodobenzylguanidine (FPOIBG). METHODS Standards of FPOIBG and 4-fluoropropoxy-3-bromobenzylguanidine (FPOBBG) as well as their tosylate precursors for labeling with (18)F, and a tin precursor for the preparation of radioiodinated FPOIBG were synthesized. Radiolabeled derivatives were synthesized by nucleophilic substitution and electrophilic iododestannylation from the corresponding precursors. Labeled compounds were evaluated for NET transporter recognition in in vitro assays using three NET-expressing cell lines and in biodistribution experiments in normal mice, with all studies performed in a paired-label format. Competitive inhibition of [(125)I]MIBG uptake by unlabeled benzylguanidine compounds was performed in UVW-NAT cell line to determine IC50 values. RESULTS [(18)F]FPOIBG was synthesized from the corresponding tosylate precursor in 5.2 ± 0.5% (n = 6) overall radiochemical yields starting with aqueous fluoride in about 105 min. In a paired-label in vitro assay, the uptake of [(18)F]FPOIBG at 2h was 10.2 ± 1.5%, 39.6 ± 13.4%, and 13.3 ± 2.5%, in NET-expressing SK-N-SH, UVW-NAT, and SK-N-BE(2c) cells, respectively, while these values for [(125)I]MIBG were 57.3 ± 8.1%, 82.7 ± 8.9%, and 66.3 ± 3.6%. The specificity of uptake of both tracers was demonstrated by blocking with desipramine. The (125)I-labeled congener of FPOIBG gave similar results. On the other hand, [(18)F]FPOBBG, a compound recently reported in the literature, demonstrated much higher uptake, albeit less than that of co-incubated [(125)I]MIBG. IC50 values for FPOIBG were higher than those obtained for MIBG and FPOBBG. Unlike the case with [(18)F]FPOBBG, the heart uptake [(18)F]FPOIBG in normal mice was significantly lower than that of MIBG. CONCLUSION Although [(18)F]FPOIBG does not appear to warrant further consideration as an (18)F-labeled MIBG analogue, analogues wherein the iodine in it is replaced with a chlorine, fluorine or hydrogen might be worth pursuing. ADVANCES IN KNOWLEDGE AND IMPLICATIONS FOR PATIENT CARE An (18)F-labeled analogue of the well-known radiopharmaceutical MIBG could have significant impact, potentially improving imaging of NET related disease in cardiology and in the imaging of neuroendocrine tumors. Although (18)F-labeled analogues of MIBG have been reported including LMI1195, we undertook this work hypothesizing that based on its greater structural similarity to MIBG, FPOIBG might be a better analogue than LMI1195.

Abstract
A tandem synthesis for structurally novel 3-chloro-4-iodoisoxazoles was developed by simply mixing 1-copper(I) alkynes, dichloroformaldoxime, and molecular iodine together. The combination of 1-copper(I) alkyne and molecular iodine was well used as a synthetic equivalent of 1-iodoalkyne without the need for tedious preparation, purification, and storage of 1-iodoalkyne.

Abstract
Mixing copper(II) perchlorate and sodium iodide solutions results in copper(I) species and the electrophilic triiodide ions, which collectively mediate the cycloaddition reaction of organic azide and terminal alkyne to afford 5-iodo-1,4-disubstituted-1,2,3-triazoles. One molar equivalent of an amine additive is required for achieving a full conversion. Excessive addition of the amine compromises the selectivity for 5-iodo-1,2,3-triazole by promoting the formation of 5-proto-1,2,3-triazole. Based on preliminary kinetic and structural evidence, a mechanistic model is formulated in which a 5-iodo-1,2,3-triazole is formed via iodination of a copper(I) triazolide intermediate by the electrophilic triiodide ions (and possibly triethyliodoammonium ions). The experimental evidence explains the higher reactivity of the in situ generated copper(I) species and triiodide ion in the formation of 5-iodo-1,2,3-triazoles than that of the pure forms of copper(I) iodide and iodine.

Abstract
Adenosine kinase (AK) catalyzes the phosphorylation of adenosine (Ado) to AMP by means of a kinetic mechanism in which the two substrates Ado and ATP bind the enzyme in a binary and/or ternary complex, with distinct protein conformations. Most of the described inhibitors have Ado-like structural motifs and are nonselective, and some of them (e.g., the tubercidine-like ligands) are characterized by a toxic profile. We have cloned and expressed human AK (hAK) and searched for novel non-substrate-like inhibitors. Our efforts to widen the structural diversity of AK inhibitors led to the identification of novel non-nucleoside, noncompetitive allosteric modulators characterized by a unique molecular scaffold. Among the pyrrolobenzoxa(thia)zepinones (4a-qq) developed, 4a was identified as a non-nucleoside prototype hAK inhibitor. 4a has proapoptotic efficacy, slight inhibition of short-term RNA synthesis, and cytostatic activity on tumor cell lines while showing low cytotoxicity and no significant adverse effects on short-term DNA synthesis in cells.

Abstract
In this paper, a new synthetic protocol for one-pot preparations of 5-halo-1,4-disubstituted-1,2,3-triazoles is provided by rational combination of a CuI catalyzed azide–alkyne cycloaddition (CuAAC) reaction and an oxidative halogenation reaction. CuI- N-chlorosuccinimide (NCS) and CuBr-NCS reaction systems are developed, respectively, for effective preparations of 5-iodo-1,4-disubstituted-1,2,3-triazoles and 5-bromo-1,4-disubstituted-1,2,3-trizoles under mild conditions with a high tolerance of various sensitive groups.
