烯丙基磷叶立德(allylic phosphorus ylides)是一类具有丰富反应性的有机中间体.由于碳负离子离域,烯丙基磷叶立德可通过γ位碳负离子参与亲核进攻,从而实现vinylogous(插烯)类型有机合成反应.综述了烯丙基磷叶立德与羰基化合物的vinylogous类型反应,具体包括vinylogous Wittig烯化反应以及多种环化反应.这些反应拓展了烯丙基磷叶立德在有机合成中的应用,并提供构筑多种重要有机功能分子的新方法.
Allylic phosphorus ylides are a class of richly reactive organic intermediates. Due to the delocalization of the carbanion, allylphosphonium ylide can participate in the nucleophilic attack via the gamma -position carbanion to achieve vinylogous ) Type organic synthesis reactions are reviewed.The vinylogous type reactions of allylphosphonium ylide with carbonyl compounds, including vinylogous Wittig olefination reactions and various cyclization reactions, are summarized.These reactions extend the application of allylphosphonium ylide in organic synthesis , And provides a new way of building molecules for many important organic functions.
