چکیده | ||
An efficient synthesis of 2H-thiopyran derivatives via three-component reaction of alkyl propiolate, benzoyl isothiocyanate or its derivatives and alkyl bromides in the presence of triphenylphosphine in water at 80o C without using any catalyst in water is described. The method offers several advantages including high yields of products and an easy work-up procedure. | ||
