Abstract:	The oxidation of 2-acetyl-5-methyl-4-R-furans (R = H, NO₂) by selenious acid was studied. Derivatives substituted at the C=O groups of the corresponding glyoxals were obtained. The nitration of 2-(5-methyl-2-furyl)quinoxaline was carried out at C_(4'). Oxidative splitting of the -nitrofuryl group occurs at the C₍₄₎-C₍₅₎ and C₍₅₎-O bonds.

Keywords:	2-acetyl-5-methyl-4-R-furans (R = H NO₂) glyoxals 2-(5'-methyl-2-furyl)quinoxaline nitric acid nitration oxidation H₂SeO₃
