• 1,2-Dihydroquinoxalines
• 1,4-Benzoxazines
• Pyrazolo[1,5-alpha]quinoxaline oxides

1,2-Dihydroquinoxaline and 1,4-benzoxazine skeletons were constructed stereoselectively from easily available aryl methyl ketones via a two-step procedure in mild conditions with high yields. Moreover, the application of this reaction provided a convenient approach to novel pyrazolo[1,5-alpha]quinoxaline oxides.
