Newer strategies for the synthesis of five and six membered heterocycles containing n o and s

Abstract

The contents of this thesis have been divided into five chapters based on the results of experimental works performed during the complete course of the research period The introductory chapter of the thesis presents an overview of different aspects of heterocyclic chemistry with special reference to five and six membered heterocycles and their synthesis using tribromides and copper catalysts Chapters 2 and 3 describe the syntheses of 1 4 dithiins and 2 iminothiazolines using a ditribromide r
