Despite the prevalence of repeating subunits in chiral natural products, stereocontrolled oligomerization is a largely unexplored strategy for construction of carbon skeletal frameworks. This report describes the use of silyl glyoxylates as dipolar glycolic acid synthons in a controlled oligomerization reaction for the efficient construction of the squalene synthase inhibitor zaragozic acid C.

尽管手性天然产物中重复亚基很普遍,但立体控制的低聚化在很大程度上是一种尚未开发的碳骨架构建策略。本报告描述了在受控低聚反应中使用甲硅烷基乙醛酸作为偶极乙醇酸合成子,以有效构建角鲨烯合酶抑制剂 zaragozic 酸 C。这种新方法允许快速、立体控制地形成具有理想保护基团方案的碳骨架,同时最大限度地减少官能团修复和氧化态操作。
