Abstract
A novel unprecedented approach for the synthesis of various quinazolinones and dihydroquinazolinones has been using [(n-Bu3Sn)2MO4]n as a catalyst. The reaction has been screened in various solvents and a gram scale experiment has also been demonstrated under given conditions. Further, the substrate scope of the reaction and the recyclability of the catalyst have also been studied.
