摘要
An efficient synthesis of β‐lactams has been expediently accomplished. These β‐lactams were synthesized by the Staudinger reaction of several substituted imines with various carboxylic acids using activated DMSO at ambient temperature. The imines and substituted acetic acids contain alkyl, aryl, hetero aryl, polycyclic, and 3‐electron‐withdrawing group underwent [2 + 2] ketene‐imine cycloaddition reaction smoothly to obtain the desired β‐lactams in good to excellent yields. This method is cheap, simple, convenient, and efficient, and the products are easily isolated.
