title: Preparation of new Schiff bases derived from beta-enaminonitriles and hetarylcarboxaldehydes. Anti-inflammatory and ulcerogenic activities.
abstract: Schiff bases 3a-j were prepared by reacting the beta-enaminonitriles (1a,b) with the appropriate hetarylcarboxaldehyde, in boiling ethanol. Structural elucidations for the new compounds (3a-j) were based upon compatible analytical and spectroscopic results. Compounds 1a, 1b, 3a, 3c, 3d and 3i were tested for their anti-inflammatory and ulcerogenic activities.
