We have synthesized the novel 2‐azetidinone derivatives by using Schiff bases of 1,2,4‐triazoles via a single step protocol. We used DABCO as a good homogenous, ecofriendly, highly reactive, easy to handle, and nontoxic catalyst. In DABCO catalyzed synthesis of active 2‐oxo‐azetidine, a highly electrophilic ketene intermediate can react with weakly nucleophilic (N═CH) linkage, which is used as the
