One Pot Synthesis of Benzopyranones and Benzoxazinones Catalyzed by MMO

Abstract

One pot synthesis of benzopyranones and benzoxazinones is aimed to develop an environment friendly strategy in which the requisite moiety is constructed by using functionality of chalcones and mixed metal oxides (MMO). MMO, as catalyst are the topic of continuing interest due to their versatile applications in the field of organic synthesis. A novel approach to the synthesis of benzopyranones and benzoxazines with high pharmaceutical activity is sought to eliminate the use of volatile organic solvents. A new methodology is designed to carry out the synthesis in a single step with enhance reaction rate with high yield.
