Abstract

A reusable heterogeneous silver nanoparticle catalyst supported on silica was used for the [3+2] cycloaddition reaction of azomethine ylides with 2'-hydroxychalcone derivatives. The green and sustainable catalytic protocol afforded highly functionalized pyrrolidines, indolizidines, and pyrrolizidines in good yields with high regio and diastereoselectivities.
