Synthesis of nitrogen oxygen and sulfur containing heterocyclic compounds

Abstract

The thesis has been presented under four chapters based on the results gathered by various experimental work undertaken during the entire tenure of the research period Chapter 1 gives an overview of some selected nitrogen oxygen and sulfur containing heterocyclic moieties their biological importance and different reported literature methods for their synthesis Chapter 2 describes a methodology for the synthesis of five six and seven membered 1 3 and 1 4 heterocyclic compounds via Intr
