The first nickel(0)-catalyzed [2 + 2 + 1] carbonylative cycloaddition reaction of imines and alkynes or norbornene has been achieved by employing phenyl formate as a CO source. With this method, a variety of N-benzenesulfonyl, -tosyl, and -phosphoryl-substituted γ-lactams can be prepared in good to high yields.
通过使用甲酸苯酯作为 CO 源,实现了第一个镍(0)催化的亚胺和炔烃或降冰片烯的 [2 + 2 + 1] 羰基化环加成反应。使用这种方法,可以高产率地制备各种 N-苯磺酰基、-甲苯磺酰基和-磷酰基取代的 γ-内酰胺。
