Abstract
Ion exchange resin catalyzed multicomponent Biginelli reaction is studied for the synthesis of 3,4- dihydropyrimidin-2-ones. Among the various solid acid catalysts Indion-130 was found to be most efficient, recyclable and environmentally benign heterogeneous catalyst regarding reaction time, yield and ease of work up procedure.
