Abstract 2‐Iminothiazolidin‐4‐one, 5‐ethylidenethiazolidin‐4‐one, and thiazolidine‐4‐thione are all medicinally relevant structures. In this work, a NaSO 2 CF 3 ‐promoted [2+2+1] cascade annulation reaction of ‐imidoyl sulfoxonium ylides isothiocyanates was reported to synthesize variety decorated thiazolidine‐4‐thiones in 35–91% yields with exclusive stereoselectivity. The gram‐scale further chemoselective S ‐alkylations demonstrated the synthetic utilities transformation.
