Bafilomycin (Baf) is one of the most potent inhibitors of vacuolar‐type ATPase, which is strongly implicated in age‐related diseases. However, the binding site of the antibiotic on the protein remains unclear because of the complexity of the structure of Baf bound to the target subunit in the transmembrane region. For conducting structural studies by applying solid‐state NMR, which is one of the most
orchestration of protecting groups is an essential requirement for the totalsynthesis 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。
