The Use of Anilinodihydrothiophenes in the Synthesis of Novel Heterocyclic Compounds.

Abstract

Base-mediated condensation of anilinodihydrothiophenes (I) and (IV) with arylidenemalononitriles provides unexpectedly the hitherto unknown ring systems (III) and (V), respectively, Reaction of (IV) with toluidine gives the expected amide (VII). -(HAMMOUDA, M.; ABOU ZEID, Z.
