Enamines 5 , prepared from heterocycles with a methyl group at a-position in respect to ring nitrogen atom 1 and N,N-dimethylformamide dimethyl acetal ( 3 ) or t-buthoxy-bis(dimethy1amino)methane (4), are transformed with 2-phenyl-5(4H)-oxazolone (1) into the corresponding intermediates 2, which cyclize into azinopyridinones 11. The method represents a novel synthesis of this class of fused systems. The formation of the latter compounds can he explained as a nucleophilic attack of the ring nitrogen atom to carhonyl group at position 5 of the oxazolone part of the molecule followed by O1-Cs bond cleavage to give the final products. The method is a novel and the only procedure by which the amino group is introduced into pyridine ring next to the carhonyl functional group.The structural assignements of fused systems are based on elemental analyses and 'H NMR spectral data. Namely, the magnitude of the coupling constants -533 -
