Abstract

Involving the cyano group of N‐cyano sulfoximines in [3+2]‐cycloaddition reactions with 1,3‐dipoles provides practical routes for the construction of 5‐membered heterocycles bearing sulfoximinoyl moieties. An ytterbium‐catalyzed cycloaddition utilizing hydrazonoyl chlorides was developed, as well as a reaction involving imidoyl chlorides proceeding without the aid of a catalyst. Following these protocols, a range of sulfoximines with N‐1,2,4‐triazolyl and N‐1,2,4‐oxadiazolyl substituents was prepared.
