SYNTHESIS AND THEORETICAL STUDY OF NEW QUINAZOLINONE DERIVATIVES CONTAINING VARIOUS HETEROCYCLIC MOIETIES

Abstract

In this work, quinazolinone derivatives were prepared, characterized by IR, UV, HNMR spectroscopy. Theoretically these compounds were studied using Hartree-Fock method and 3-21G basis set, where it was found HOMO-LUMO and thermodynamic functions (Hof , Gof and Sof) calculations, which found from values of these functions that the reactions of quinazolinone derivatives synthesis were exothermic reaction.
