Total synthesis of (–)-L-batzellasides A, B, and C has been achieved in 13 steps from known lactone 2 in 12.6, 13.2, and 13.8 % overall yields, respectively. The key steps in this synthesis were the stereoselective introduction of an allyl group at the C1 position by acyliminium chemistry and Brown's asymmetric allylation of the corresponding aldehydes to construct a stereocenter on the side chain
(-)-L-batzellasides A、B 和 C 的全合成已通过 13 个步骤从已知的内酯 2 中实现,总产率分别为 12.6、13.2 和 13.8%。该合成的关键步骤是通过 acyliminium 化学在 C1 位置立体选择性地引入烯丙基,以及布朗对相应醛的不对称烯丙基化以在侧链上构建立体中心。
