Abstract

Abstract : An organobase-controlled, regiodivergent (3+2) cycloaddition resulting in two different cascade reactions is demonstrated from azomethine ylides and 2-hydroxybenzylidineindandiones to achieve diverse chromanopyrrolidines. Abstract : An organobase-directed, regiodivergent 1, 3-dipolar cycloaddition of azomethine ylides and 2-hydoxybenzylidene indandiones is reported. The scarcely explored reversal of the nucleophilic site in azomethine ylides has been exploited for their regiodivergent (3+2) cycloaddition, which subsequently resulted in two different cascade processes to generate functionally distinct chromenopyrrolidines in a diversity oriented manner.
