## Abstract We report the synthesis of a class of 4‐(2‐oxoethylidene)azetidin‐2‐ones by a novel Lewis acid mediated reaction of acyldiazo compounds with 4‐acetoxyazetidin‐2‐ones. Using this approach, C‐3‐and C‐4‐substituted 4‐alkylideneazetidin‐2‐ones were obtained depending on the choice of starti
