Abstract

A novel copper-catalyzed cascade synthesis of thiazolidine-2-thiones from N-(2-bromoallyl)amines and carbon disulfide has been developed. The procedure combines carbamodithioic acid formation and copper-catalyzed intramolecular S-vinylation in one sequence. By elevating the temperature, the one-pot reaction efficiently affords thiazole-2(3H)-thiones in moderate to good yields.
