Abstract

Synthesis of Some p-quinones Derivatives

A group of α, β- unsaturated carbonyl compounds were prepared as intermediates by the reaction of para aminoacetophenone with various aromatic aldehydes in the presence of NaOH in ethanol at room temperature. The products were cyclised with hydroxylamine hydrochloride under reflux condition to form isoxazoles derivatives, which were allowed to react with 2,3,5,6-tetrabromo-1,4-Benzoquinone in order to furnish the target compounds i.e.(p-quinones derivatives). The structures of the prepared compounds were confirmed by elemental analysis IR,1HNMR and Ms.
