چکیده
|
3-arylhydrazono-2,4-dioxo-4-phenylbutanoates has been prepared by the coupling of benzoyl pyruvicester with aryldiazonium chlorides. 3-arylhydrazono-2,4-dioxo-4-phenylbutanoates reacts with 1,2-phenylenediamine,2-aminophenol, and 2-aminothiophenol, to form the corresponding quinoxaline, 1,4-benzoxazine, and 1,4-benzothiazinederivatives. interaction of 3-arylhydrazono-2,4-dioxo-4-phenylbutanoates with 2,3-diaminopyridine,1,2-ethelenediamine, and 1,2-diaminohexane results in pyrazine products. the structure of the resulted productswere confirmed by determination of the melting point and spectrophotometric techniques such as ir and 1h nmrand in some cases by using 13c-nmr spectroscopy.
