achievements of catalytic carbonyl–olefin metathesis (CCOM) mediated by Lewis acid catalysts, exploration of the CCOM through Brønsted acid-catalyzed approaches remains quite challenging. Herein, we disclose a synthetic protocol for the construction of a valuable polycycle scaffold through the CCOM with the inexpensive, nontoxic phosphomolybdic acid as a catalyst. The current annulations could realize carbonyl–olefin
与由
路易斯酸催化剂介导的催化羰基烯烃复分解(CCOM)的令人印象深刻的成就相比,通过布朗斯台德酸催化的方法探索 CCOM 仍然相当具有挑战性。在这里,我们公开了一种合成方案,用于通过 CCOM 以廉价、无毒的
磷钼酸为催化剂构建有价值的多环支架。目前的环化可以实现羰基-烯烃、羰基-醇和
缩醛-醇原位CCOM反应,并且具有反应条件温和、操作简单和可扩展性等特点,使该策略成为
路易斯酸催化COM反应的有希望的替代方案。
