The totalsynthesis of solandelactones A and B is presented. The eastern cyclopropyl moiety was prepared following an exceptionally short chemoenzymatic approach whereas enantioselective synthesis of the western side-chain relied on the application of diastereomerically pure allyl boronates. The natural products solandelactones A and B were isolated in good overall yields following convergence of each
介绍了茄内酯 A 和 B 的全合成。东部环丙基部分是按照非常短的化学酶促方法制备的,而西部侧链的对映选择性合成依赖于非对映异构纯硼酸烯丙酯的应用。通过应用 Nozaki-Hiyama-Kishi 反应将每个东西元素收敛后,天然产物茄内酯 A 和 B 以良好的总产率分离。
