A stereocontrolled total synthesis of the orthinine decarboxylase inhibitors saliniketals A and B is described. Key features of the 17-step route include the use of two boron aldol/reduction sequences to control six of the nine stereocenters, an intramolecular Wacker-type cyclization to install the bicyclic acetal core, and a late-stage Stille coupling to append the requisite (2 Z,4 E)-dienamide.
描述了鸟氨酸脱羧酶抑制剂水杨酮A和B的立体控制的总合成。17步路线的主要特征包括使用两个硼醇醛/还原序列控制9个立体中心中的6个,分子内Wacker型环化以安装双环乙缩醛核以及后期Stille偶联以添加必需的(2 Z,4 E)-二酰胺。
