A facile catalyst and solvent-free synthesis of spiro thia heterocycles on grinding

Abstract

An efficient and mild method for the synthesis of spiro [1,3- oxathiolan/oxathianes] in the solid state reaction at room temperature has been described. This method is a good option to obtain the title compounds in quantitative yields in a simple and inexpensive way. Applying this methodology, different thia heterocycles were synthesized.
