Abstract

A facile and one step route for the synthesis of substituted pyrroie derivatives 5a-g from reaction of ethyl arylidenecyanoacetate (1) with glycine (2) was reported. Also the pyrrolidone derivative ,12 was formed upon reaction of benzylidenemalononitrile (7) with 2 The synthesized 5 has been used as a precursor in the syntheses of pyrrolo[3,4-c]pyrazole 13, pyrrolo[3,2-b]pyridine 15 or its tautomer 16 and pyrrolo[3,2-b]pyrrole derivatives 18.
