An enantioselective total synthesis of (+)-peloruside A (1) is described. Peloruside A (1) is a potent microtubule stabilizer with significant clinical potential. The synthesis is convergent and involves the assembly of C1-C10 segment 2 and C11-C24 segment 3 by a novel aldol protocol followed by Yamaguchi macrolactonization of the resulting seco-acid, selective methylation of hemi-ketal and removal of the protecting groups to peloruside A.
本文描述了(+)-海葵毒素A(1)的对映选择性全合成。海葵毒素A(1)是一种具有显著临床潜力的强效微管稳定剂。该合成是汇聚式的,包括通过一种新颖的羟醛反应方案组装C1-C10片段2和C11-C24片段3,随后对所得的半缩醛酸进行山口大环内酯化反应,对半缩酮进行选择性甲基化,并去除海葵毒素A的保护基团。
