Newer strategies for the synthesis of mono and bicyclic oxygen heterocycles

Abstract

The thesis contains six chapters The first chapter provides a brief introduction about monoand bicyclic oxygen heterocycles and oxonium ene cyclization reactions Special emphasis has been given to six membered oxygen heterocycles and oxabicyclic compounds The second chapter gives a description about the novel synthesis of oxabicyclo 3 3 1 nonanone via 3 5 oxonium ene reaction The third chapter describes about the synthesis of oxabicyclo 3 3 1 nonenes and substituted tetrahydropyrans via 3
