The total synthesis of doliculide (1), a potent cytotoxic cyclodepsipeptide from the Japanese sea hare Dolabella auricularia, has been achieved. The key step of the synthesis is the construction of the stereogenic centers of a 15-carbon polyketide-derived dihydroxy acid moiety by a combination of the Evans aldol reaction and the Barton deoxygenation reaction. Furthermore, artificial congeners of doliculide
来自日本海兔Dolabella auricularia的有效的细胞毒性环二肽doliulide(1)的总合成已实现。合成的关键步骤是通过结合Evans aldol反应和Barton脱氧反应来构建15碳聚酮化合物衍生的二羟基酸部分的立体中心。此外,合成了人工合成的杜立舒利德,并检查了结构与细胞毒性的关系。
