sequence involves the reaction of cycloprop-2-ene carboxylic acids with unsaturated amines to furnish amides, which are further subjected to a Cu-catalyzed directed carbomagnesiation and a ring-closing olefin metathesis reaction. This methodology allows for the efficient preparation of lactams with ring sizes up to 10.
描述了一种用于中型杂环组装的快速单击-单击环化策略。该序列涉及环丙-2-烯
羧酸与不饱和胺的反应以提供酰胺,其进一步经受Cu催化的直接碳还原反应和闭环烯烃复分解反应。这种方法可以有效制备环大小最大为10的内酰胺。
