摘要
A palladium‐catalyzed [3+2] annulation reaction of N‐sulfinylanilines with vinylethylene carbonates and vinyl epoxides is developed. It affords 1,2,3‐oxathiazolidine‐2‐oxides under mild reaction conditions through allylic palladium intermediates. The versatile synthetic utility of 1,2,3‐oxathiazolidine‐2‐oxides in preparing sulfoxides, β‐amino alcohols, and substituted amines has also been demonstrated.
