The synthesis and SAR of novel diarylsulfone 11β-HSD1 inhibitors
摘要:
In this communication, human 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) inhibitory activities of a novel series of diarylsulfones are described. Optimization of this series resulted in several highly potent 11b-HSD1 inhibitors with excellent pharmacokinetic (PK) properties. Compound (S)-25 showed excellent efficacy in a non-human primate ex vivo pharmacodynamic model. (C) 2010 Elsevier Ltd. All rights reserved.
通过过渡金属催化或 S N Ar 反应制备S -芳基黄原酸酯因其在所用条件下的进一步转化而变得复杂。相比之下,O-烷基黄原酸钾与二芳基碘盐的 S-芳基化反应在温和条件下进行,从而能够获得取代的S-芳基黄原酸。该方法表现出良好的官能团耐受性,可应用于药物分子的后期C-H功能化。由此产生的S -芳基黄原酸酯的不同转化提供了快速获得一系列与药物化学相关的有机硫化合物的途径。

Disclosed is a mild, scalable, visible-light-promotedcross-couplingreaction between thiols and aryl halides for the construction of C-S bonds in the absence of both transition metal and photoredox catalysts. The scope of aryl halides and thiol partners includes over 60 examples and therefore provides an entry point into various aryl thioether building blocks of pharmaceutical interest. Furthermore

In one aspect, the invention provides a method of promoting a carbon-sulfur bond forming reaction. In certain embodiments, the reaction comprises cross-coupling of a(n) (hetero)aryl halide with a thiol to form the carbon-sulfur bond, wherein the method is promoted by light irradiation in the absence of a photocatalyst. In other embodiments, the cross-coupling reaction can be promoted through visible light irradiation, including sunlight.
