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

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
