The first asymmetric total synthesis of the marine natural product apratoxin D, a highly potent inhibitor of H-460 human lung cancer cell growth (IC50 value of 2.6 nM), is described. Asymmetric N-amino cyclic carbamate (ACC) α,α-bisalkylation was utilized to establish the isolated C-37 methyl group with excellent selectivity. Other key asymmetric transformations employed were an Evans syn-aldol and
描述了海洋天然产物pratoxin D(H-460人肺癌细胞生长的强效抑制剂(IC 50值为2.6 nM))的第一个不对称全合成。利用不对称的N-氨基环状氨基甲酸酯(ACC)α,α-双烷基化反应以优异的选择性建立了分离的C-37甲基。使用的其他关键的不对称转化是Evans syn- aldol和Paterson anti- aldol,它们都以优异的立体选择性进行。
