The stereoselective synthesis of malyngamide M (1) was accomplished in nine steps from o-cresol in 12% overall yield. The key steps involved the Wittig reaction of an α-NHBoc aryl ketone 4 for the introduction of vinyl chloride functionality, an amidation of lyngbic acid 3 with a secondary amine 2 for the framework of target molecule, and an isomerization of a (Z)-vinyl chloride to the (E)-configuration
麦芽酰胺M(1)的立体选择性合成是从邻甲酚开始的9个步骤,总产率为12%。关键步骤包括用于引入氯乙烯官能团的α- NHBoc芳基酮4的Wittig反应,针对目标分子框架的lyngbic acid 3与仲胺2的酰胺化以及(Z)-的异构化使用二苯甲酮作为光敏剂将氯乙烯制成(E)-构型。还合成了异麦芽酰胺M(Z - 1)。
