Unexpected Reduction of Ethyl 3-Phenylquinoxaline-2-carboxylate 1,4-Di-N-oxide Derivatives by Amines(†)
The unexpected tendency of amines and functionalized hydrazines to reduce ethyl 3-phenylquinoxaline-2-carboxylate 1,4-di-N-oxide (1) to afford a quinoxaline 1c and mono-oxide quinoxalines 1a and 1b is described. The experimental conditions were standardized to the use of two equivalents of amine in...
