摘要：

The reaction of 6-chloro-2-hydrazinoquinoxaline 4-oxide Ib with acetylacetone or benzoylacetone gave 6-chloro-2-(3,5-dimethylpyrazol-1-yl)quinoxaline 4-oxide 5a or 6-chloro-2-(3-methyl-5-phenylpyrazol-1-yl)quinoxaline 4-oxide 5b, respXectively. Compound 5a or 5b was converted into the pyrrolo[1,5-a]quinoxaline 6a or 6b, triazolo[4,3-a]quinoxaline 9a or 9b, and tetrazolo[1,5-a]quinoxaline 10.
