A NBS-mediated sequential one-pot synthesis of multifunctionalized thiazoles and thiophenes from 1,3-dicarbonyl compounds and mercaptonitrile salts has been developed under mild conditions. This transformation involves sequential bromination/SN2 alkylation/Thorpe–Zieglercyclization/regio-selective elimination of a –COR group, affording the desired products in moderate to good yields. The sequence
由NBS介导的从1,3-二羰基化合物和硫醇腈盐开始的多官能噻唑和噻吩的顺序一锅法合成已经在温和的条件下进行。该转化涉及顺序溴化/ S N 2烷基化/索普-齐格勒环化/ -COR基团的区域选择性消除,以中等至良好的收率提供所需的产物。确定了-COR基团离去反应的顺序,并提出了可能的机制。
