A general skeletal ring expansion strategy for the direct conversion of aziridines into 2-vinyl azetidines via one-carbon insertion using vinyl-N-triftosylhydrazones is described. The method is scalable, tolerates diverse functional groups, and is amenable to the synthesis of medicinally relevant molecules.
