摘要:
Proceeding from 2-aminoquinoxaline-3-carbonitrile 1,4-dioxides new derivatives of quinoxaline and quinoxaline 1,4-dioxide were synthesized containing in the position 3 of the quinoxaline fragment 1,2,4-oxadiazole and tetrazole rings. The acylation of 2-amino-N'-hydroxyquinoxaline-3-carbox imidoamide 1,4-dioxide was investigated.
