6-NITRO-2,3-DIPIPERIDINOQUINOXALINE: ITS UNEXPECTED FORMATION FROM 2-CHLORO-7-NITROQUINOXALINE

Excess piperidine and 2-chloro-7-nitroquinoxaline 1 in diethyl ether give large amounts of the unexpected disubstitution product 6-nitro-2,3-di-piperidinoquinoxaline 3.The mechanism of this very unusual nucleophilic substitution of hydrogen is suggested to involve the oxidation of the dipiperidino-dihydroquinoxaline 10 by dissolved oxygen.

Methodologies to obtain quinoxaline compounds regioselectively are rarely reported in literature, thus regioselective and multi-gram methodologies to obtain these derivatives are desirable to explore the entire potential of these scaffolds for academic and/or commercial application. A facile and multi-gram methodology is described to obtain compound 7-nitroquinoxalin-2-amine using o-phenylenediamine, a cheap and readily available reactant, as starting material in a five-step procedure in good yields and high purity without further purification such as crystallization or column chromatography.
