Abstract Diethyl-3-amino-2-cyano-2-pentendioate (1) reacts with aromatic amines and aminohetero-cyclic compounds to yield amide derivatives (2 c-h). The latter derivatives were utilised in synthesis of pyridazines (4a, b), pyrimidine (6), pyridone (9) and pyrano[4,3-b]pyridine (16a, b) derivatives via reaction with aryldiazonium chloride, trichloroacetonitrile, sodiummethoxide and cinnamonitrile derivatives, respectively.
