Expeditious solvent-free synthesis of 1,3-thiazolanes via multicomponent reactions

A series of 1,3-thiazolane derivatives have been synthesized via multicomponent reactions of activated acetylenes, primary amines and isothiocyanates in the presence of a catalytic amount of N-methylimidazole under solvent-free conditions.
