An atom economical and environmentally benign protocol has been developed for the regioselective C(sp2)–H bond functionalization of indolizines. The acetic acid-catalyzed cross-coupling reaction proceeds undermetal-freeconditions, producing a wide range of synthetically useful indolizine derivatives. The present protocol showed good functional group tolerance and broad substrate scope in good to
herein present an electrochemical method for the dehydrogenativecross-coupling of N-(4-hydroxyphenyl)-sulfonamides and 2-naphthols. This transformation provides a direct and scalable approach to a wide range of C1-symmetric 2,2′-bis(arenol)s with moderate to high yields under mild conditions. Preliminary attempts with the asymmetric variant of this reaction were also performed with ≤55% ee for the synthesis
我们在此提出了一种用于 N-(4-羟基苯基)-磺胺类药物和 2-萘酚脱氢交叉偶联的电化学方法。这种转化为在温和条件下以中高产率分析各种 C1 对称 2,2′-双(芳烃醇)提供了一种直接且可扩展的方法。还用 ≤55% ee 对该反应的不对称变体进行了初步尝试,以合成 2,2′-双(芳烃醇)。进行了对照实验以提出一种合理的反应机制。
