Abstract
This paper presents a combined synthesis and computational study of novel series of pyridones, quinazolinones and pyrazoles heterocyclic compounds that were characterized by elemental analyses and spectral dada. Michael addition of substituted-2-methoxycarbonylacetanilide 2a, b on the alpha-substituted cinnamonitriles 3a-d gave the corresponding pyridone and quinazolinone derivatives 5, 6a-c, 7a-d, and 14a-e, respectively. Reaction of ethyl-2-cyano3-ethoxyacrylate with 2a, b afforded the corresponding pyridone 10a, b. Also, spiro pyridine derivative 12 was synthesized through the reaction of 2a, b with indandione malononitrile (11). Reaction of hydrazine and phenyl hydrazine with acrylamido derivatives 15a-d afforded the novel pyrazoles 16 and 17. The molecular modeling of the synthesized compounds has been drawn and their molecular parameters were calculated. Also, valuable information is obtained from the calculation of molecular parameters including electronegativity of the coordination sites, net dipole moment of the compounds, total energy, electronic energy, binding energy, HOMO and LUMO energy.
