Organocatalytic asymmetric synthesis of oxygen nitrogen and sulfur heterocycles

Abstract

Asymmetric organocatalysis is an economical and environment friendly process where a purely organic small molecule is used to catalyze organic transformations Most of the naturally occurring compounds are optically active they are not superimposable on their mirror images Moreover the different enantiomers can have different odor taste and more importantly different pharmacological properties The thesis have been divided into six chapters Chapter 1 contains a brief discussion on asymmetri
