Synthesis of novel 3,4‐dihydropyrimidinones on water soluble solid support catalyzed by indium triflate
TL;DR: The microwave enhanced rapid synthesis of 3,4-dihydropyrimidinones (DHPMs) on solid support has been reported in this article, where the mechanism of the reaction is expected to proceed via absorption of substrates on the solid support followed by promotion by In(OTf)3 coupled with microwave irradiation.
