Abstract

The o-aminobenzylidene derivative (IIc) of 2H, 3H-thieno [3, 2-b] pyrrol-3-one(I) undergoes cyclization to the novel heterocyclic compound 111 composed of linearly fused pyrrole, thiophene, pyridine and benzene rings. By the action of acetic anhydride the o- aminobenzylidene derivative IIc is converted into a triacetyl derivative I-, which is hydrolyzed to a monoacetyl derivative VI, and the polynuclear heterocyclic compound I11 is acylated ...
