The highly stereoselective total synthesis of the macrolide antibiotic, bafilomycin A(1) (1), the first specific potent inhibitor of vacuolar H(+)-ATPase, has been achieved by a convergent route involving the synthesis and coupling of its 16-membered tetraenic lactone and beta-hydroxyl hemiacetal side-chain subunits. The C1-C17 16-membered lactone aldehyde 2 was synthesized through the coupling of
大环内酯类抗生素bafilomycin A(1)(1),液泡H(+)-ATPase的第一个特效抑制剂的高度立体选择性总合成,已通过涉及其16元成员的合成和偶联的聚合途径实现四烯内酯和β-羟基半缩醛侧链亚基。通过将C5-C11乙烯基碘化物4和C12-C17乙烯基锡烷5偶联,然后构建C1-C4二烯并进行大内酯化来合成C1-C17 16元内酯醛2。2和C18-C25乙基酮3的醛醇缩合偶联,然后进行去甲硅烷基化反应,得到的1与天然巴菲霉素A(1)相同。关键的合成链段3-5是由易于获得的手性材料D-葡萄糖,(S)-乳酸乙酯和(S)-3-羟基-2-甲基丙酸甲酯有效合成的,
