Utility of Benzoxazin-4-one and 3-Aminoquinazolin-4-one Derivatives as Precursors for Construction of Potent Insecticidal Heterocycles

Abstract

In demanding to develop new insecticidal agents, both of 2-pentylbenzoxazin-4-one 1 and 3-amino-2- pentylquinazolin-4-one 6 derivatives were subjected to react with different nucleophilic agents, for example, ammonia, o-phenylenediamine, hydrazine hydrate, and hydroxylamine hydrochloride, and sulfur nucleophile, for example, phosphorous pentasulfide, to construct different heterocyclic systems. The structural elucidations of the synthesized compounds were ascertained from the elemental analyses and the spectral data. Assessment of the biological potency for some of the synthesized compounds as insecticidal agents was evaluated against two different insects named Mythimna separata and Nilaparvata lugens
