The formal total synthesis of (−)-spongidepsin is described. Three fragments I, II, and III were first prepared from readily available starting materials and then assembled to the target compound. The key steps involved in the synthesis are asymmetric α-hydroxylation, Ender's alkylation, and ring-closing metathesis reactions. An alternative route for the fragment II is also achieved involving Sharpless
描述了(-)-海绵蛋白酶的正式全合成。首先从容易获得的起始原料中制备三个片段I,II和III,然后组装成目标化合物。合成中涉及的关键步骤是不对称α-羟基化,Ender烷基化和闭环易位反应。还实现了片段II的替代途径,其中涉及Sharpless不对称环氧化和吉尔曼烷基化作为关键反应。
