Synthesis of the acyl side-chain and amino acid (2S,3R)-3-hydroxy-3-methylproline units of the potent depsipeptide polyoxypeptin A, is described. Key intermediates were secured via diastereoselective addition involving a homoenolate ion and allylation of an aminoketone, respectively.
描述了强效缩肽聚氧肽素 A 的酰基侧链和氨基酸 (2S,3R)-3-羟基-3-甲基脯氨酸单元的合成。关键中间体通过非对映选择性加成获得,分别涉及同烯醇化物离子和氨基酮的烯丙基化。
