Enamines 6, prepared from heterocycles with a methyl group at α-position in respect to ring nitrogen atom 1 and N,N-dimethylformamide dimethyl acetal (3) or t-butoxy-bis(dimethylamino)methane (4), are transformed with 2-phenyl-5(4H)-oxazolone (7) into the corresponding intermediates 9, which cyclize into azinopyridinones 11.The method represents a novel synthesis of this class of fused systems.
