were achieved via an aza-Belluš–Claisen rearrangement, which involved the reaction of an α-chloro carboxylic acid chloride with halogen-substituted trans-allyl morpholines in the presence of Lewis acids. The developed method was used for the total synthesis of a group of monoterpene natural products bearing vicinal dichloride subunits.
顺和反邻位二卤化物的非对映选择性合成是通过氮杂-贝卢什-克莱森重排实现的,该重排涉及在路易斯酸存在下,α-氯代羧酸氯化物与卤素取代的反式烯丙基吗啉反应。所开发的方法用于全合成一组带有连二氯亚基的单萜天然产物。
