Abstract

A Simple and Convenient Synthesis of 4-Ylidene-5(4H)oxazolone Derivatives: Oxazolone Ring Transformation Leading to Other Heterocyclic Structures. -The title compounds (III) are obtained from arylidene-malononitriles under solvent--free conditions. Compound (IIIi) undergoes ring transformation into pyrroles, imidazoles, pyridazine, and triazines. -(ABDEL-MOTALEB, R. M.; BAKEER, H. M.; TAMAM, G. H.; ARAFA*, W. A. A.; J. Heterocycl.
