Utility of p-phenylenediformamidine in the synthesis of bisazoles and phenanthroline

(Chemical Equation Presented) p-Phenylenediformamidine 1 is readily obtained upon treating p-phenylenediamine with dimethylformamide dimethyl acetal (DMFDMA) by heating or by microwave irradiation. Compound 1 was treated with active methylene nitriles fol

Synthesis of pyrrole, pyridinone and pyrimidinone derivatives using PTC conditions

The reaction of anilinomethylenemalononitrile 1 or 1,4-di(malononitrilemethyleneamino)benzene 7 with some reactive halo compounds in a one-pot reaction under PTC conditions affords a new series of pyrrole and pyridinone compounds. The reaction of compounds 1 or 7 with ethyl chloroformate gives the corresponding esters which underwent cyclization on reaction with different amino compounds affording the pyrimidinone derivatives.
