Synthese Des 2,3-Di(Pyrazolyl, Isoxazolyl et 1,2,3-Triazolyl) Methylsulfanylquinoxalines

Abstract

A one pot synthetic approach to the novel (pyrazolyl, isoxazolyl, triazolyl) methylsulfanylquinoxaline system respectively by 1,3-dipolar cycloaddition of diphenylnitrilimine, benzonitriloxide and benzylazide to 2,3-dipropargylmercaptoquinoxaline, is described. The structures of the obtained adducts have been assigned by means of spectroscopic measurements.
