Abstract
The paper describes opening of isoxazole ring with 1,2-diaminobenzene leading to 2-cyanomethylene-3-oxo-1,2,3,4-tetrahydroquinoxaline and preparation of its derivatives. Synthesis have been studied of substituted 3,4-dihydro-3-oxo-quinoxaline-oxides, and tautomers of 1-oxides of 2-ethoxycarbonylmethylquinoxalines have been obtained.
