A highly stereoselective total synthesis of the macrolide antibiotic concanamycin F (1), a specific and potent inhibitor of vacuolar H(+)-ATPase, has been achieved by a convergent route involving the synthesis and coupling of its 18-membered tetraenic lactone and beta-hydroxyl hemiacetal side chain subunits. The C1-C19 18-membered lactone aldehyde 4 was synthesized through the intermolecular Stille
大环内酯类抗生素伴刀豆球蛋白F(1),液泡H(+)-ATPase的特异性和强效抑制剂,具有高度立体选择性的总合成,已通过一条涉及其18元四烯内酯和β的合成和偶联的聚合途径实现。 -羟基半缩醛侧链亚基。C1-C19 18元内酯醛4是通过C5-C13乙烯基碘24和C14-C19乙烯基锡烷25的分子间Stille偶联合成的,然后构建C1-C4二烯并进行大内酯化。还实现了通过第二种收敛途径合成4,包括C1-C13乙烯基碘化物45和C14-C19乙烯基锡烷47的酯化,然后进行分子内Stille偶联。
