Syntheses of fused heterobicyclic systems containing 1,2,4-triazolopyridinone moieties were accomplished by heterocyclization of 1,6-diamino-2-oxo-4-phenyl-1,2-dihydropyridine-3,5-dicarbonitriles and ninhydrin in ethanol and in the presence of boric acid as a catalyst in 30?min at room temperature. All compounds have been screened for their photophysical properties. Results showed that all compounds exhibit near infrared emissions at 876?nm.

Synthesis of 1,6-diamino-4-phenyl-3,5-dicyano-2-pyridone derivatives via a one-pot, three-component reaction of aryl aldehydes, malononitrile, and cyanoacetic hydrazide at room temperature using KF-Al2O3 as a recyclable catalyst have been developed. The reaction proceeds through the initial Knoevenagel condensation between aldehyde and malononitrile in the presence of KF-Al2O3 to form the benzylidene derivative which then undergoes Michael addition with cyanoacetic hydrazide followed by intramolecular cyclization of the resulting intermediate to produce the N-amino-2-pyridones in good to excellent yields. The structure of the synthesized compounds were characterized and established on the basis of their spectral data analysis and single-crystal XRD analysis.

A simple and convenient protocol has been developed for the synthesis of N-amino-3-cyano-2-pyridone derivatives by a one-pot reaction of cyanoacetohydrazide, activated nitrile substrates (malononitrile, ethyl cyanoacetate, cyanoacetamide) and aromatic ald
A simple route for the synthesis of pyrano[2,3-c]pyrazole and pyridine-2-one derivatives

, p. 736 - 738 (2007/10/02)
A series of pyrano[2,3-c]pyrazoles and pyridine-2-ones were prepared through the ternary condensation of aldehydes with malononitrile and 3-methyl-1-phenyl-2-pyrazoline-5-one or 3-amino-2-pyrazolin-5-one or cyanoacetic acid hydrazide. Structure and reacti
