Synthesis of indanone based spirocyclic molecules following 13-dipolar cycloaddition reaction consists of two chapter. Chapter I deals withone pot three component synthesis of spiroindenoquinoxaline pyrrolidine fused nitrochromene derivatives following 13-dipolar cycloaddition. Chaapter II deals with one pot three component 13-dipolar cycloaddition: Regio and diastereoselective synthesis of spiropyrrolidinyl indenoquinoxaline based chromene nitrile derivatives.
