a potent antitumor agent, is synthesized stereoselectively in a convergent manner. The key strategy involves a stereoselective synthesis of the polyketide unit and synthesis of the D-tyrosine derivative, followed by assembly of the fragments by an esterification and cycloamidation reaction sequence. The synthesis of the polyketide fragment was achieved by an iterative asymmetric synthesis to install
[反应:见正文](-)-Doliculide是一种有效的抗肿瘤药,它是通过收敛方式立体选择性合成的。关键策略涉及聚酮化合物单元的立体选择性合成和D-酪氨酸衍生物的合成,然后通过酯化和环酰胺化反应序列组装片段。聚酮化合物片段的合成是通过迭代不对称合成来实现的,该合成过程中以不对称环丙烷化和Sharpless不对称环氧化为关键步骤,立体选择性地安装了1,3-二甲基和1,3-二醇单元。
