## Abstract Pd‐catalyzed cyclization of trifluoromethylimidoyl chlorides (I), (III) represents a novel efficient access towards trifluoromethyl‐substituted benzothiazoles (II).
An efficient, three-step synthesis of N-vinyl-2-azetidinones 7 selenylation, and finally m-CPBA treatment, afforded Nvinyl-2-azetidinones 7 in fair to excellent yields, with starting from αor β-amino ester imines 4 has been developed. Staudinger reaction between imines 4 and a retention at the remai
