A simple and efficient stereoselective total synthesis of desacetylumuravumbolide (1a) and umuravumbolide (1b), starting from commercially available valeraldehyde has been described. The synthetic strategy involves a highly enantioselective zinc-mediated addition of protected 2 alkyn-1-ol to aldehyde, a Crimmins aldol reaction, and Horner–Wadsworth–Emmons olefination as key steps.
已经描述了一种从市售戊醛开始的去乙酰基umuravumbolide(1a)和umuravumbolide(1b)的简单有效的立体选择性全合成。合成策略包括高度对映选择性锌介导的受保护的 2 alkyn-1-ol 与醛的加成、Crimmins 醛醇反应和 Horner-Wadsworth-Emmons 烯化作为关键步骤。
