Abstract

This review aims at giving a brief summary on the preparation of three and four membered heterocycles laying particular emphasis on the various green approaches for the synthesis of substituted aziridines, thiiranes, β-lactams, diones and thietanes. The review presents the result of our literature survey of the work done in recent years on the use of solid support catalyzed reaction and more environmentally benign approaches for three and four membered heterocyclic synthesis.

Keywords: Aziridines, thiiranes, lactams, non-volatile solvents, ionic liquids
