This book contains literature data of previous work done on azomethine ylide mediated 1,3 dipolar cycloaddition reaction and based on that synthesis of pyrrolo-indole and isoquinolines. Synthesized compounds have been identified by spectral analysis using 2D NMR, DQF-COSY and NOESY, and single crystal X-ray diffraction studies their biological essay to analyse their potency and application.This book is helpful for post graduate level students and researchers of Organic chemistry to provide them detailed information and knowledge regarded 1,3 dipolar cycloaddition reaction via azomethine ylide.
