Development of greener coupling reagents and methodologies for the syntheses of esters amides and peptides

Abstract

The contents of this thesis have been divided into six chapters Chapter 1 contains the introduction Chapter 2 contains the detailed studies on the halogen free synthesis of sulphonates of alcohol Oxyma O sulphonates and oxime O sulphonates under microwave irradiation Chapter 3 contains our works on the greener approach towards the synthesis of amides and esters using the catalytic amount of o NosylOXY Chapter 4 contains the racemization free synthesis of peptides and polypeptides using the
