orchestration of protecting groups is an essential requirement for the total synthesis of the macrolide antibiotic bafilomycin A1 (1). Key steps were the Suzuki cross-coupling reaction of two advanced, suitably protected intermediates prior to closure of the macrocycle, as well as a highly stereoselective methyl ketone aldol reaction.
精心策划保护基团是大环内酯类抗生素bafilomycin A 1(1)的全合成的基本要求。关键步骤是在封闭大环之前,两个先进的,适当保护的中间体的Suzuki交叉偶联反应,以及高度立体选择性的甲基酮醇醛缩合反应。
