Overview
In this second edition, the author has thoroughly updated each chapter and expanded the content with addition of three new chapters. This book comments on several key aspects of stereochemical control of organic reactions in measured detail to allow the reader easily grasp these concepts. In addition, emphasis is given to key information and important aspects of steric and stereoelectronic effects and their control on conformational profile and reactivity features. This book is not only an indispensable resource for advanced undergraduate and graduate students studying the stereochemical aspects of organic reactions, but also a good reference book for all organic chemists in both industry and academia.

Author Information
Veejendra K. Yadav earned his PhD under the mentorship of Dr. Sukh Dev in 1982. He carried out his postdoctoral research at University of Calgary, Memorial University of Newfoundland, University of Ottawa, and University of Southern California over the years 1983-1990 before joining Indian Institute of Technology Kanpur (IITK) as Assistant Professor in late 1990. Over the years, he rose through ranks and became full Professor in 2001. He has taught both undergraduate and postgraduate students at IITK over the past thirty years, and has remained a popular teacher among the students throughout. His research focuses on development of new reactions with emphasis on the construction of pharmacophores, synthesis of biologically active molecules, computational-cum-experimental investigation of facial selectivity, and computational investigation of reaction mechanisms. He has three international patents and 100 research papers in peer reviewed journals to his credit.
