Transition metal and oxidant free sustainable syntheses of heterocyclic molecules

Abstract

The thesis describes synthesis of various heterocyclic compounds without any transition metal or external oxidant In chapter 1 importance of heterocyclic molecules and their synthesis by different strategies have been discussed Chapter 2 highlights synthesis of heterocycles via aerobic oxidation of 2 hydroxyacetophenones without any need of redox catalyst system We have been able to synthesize phthalides quinoxalines 206 177 ketoamides under mild reaction condition Catalytic amount of base ac...
