(Alpha)-3-Arylidene-5-[2¢-(p-cymyl]-spirofuran-3(2H)-2-ones (1a-d) were reacted with primary amines and gave cinnamamide derivatives (1Va-h) which were cyclized by the action of acetic anhydride and yielded the desired pyrolin-5-ones (VA-h). also (1a,b) were reacted with aromatic amines and anthranilic acid, the products pyrolin-5-one derivatives (Vi-n) were obtained.Action of ethanolic hydrazine hydrate on (Ia-d), (II) and (IIIa,b) were investigated either at room temperature or in boiling ethanol. Sodium hydroxide was affected on (IVi-I) and gave (Vla-d) also (VII) was condensed with benzaldehyde and yielded (IX). Cyclization of (VII) and (X) were investigated. All the structures of the adducts were confirmed via either analytical data or spectroscopic possible tools.
