摘要
3-[(Z)-3,3-Dimethyl-2-oxobutylidene]-3,4-dihydroquinoxalin-2(1H)-one and its 1-phenyl-substituted analog reacted with oxalyl chloride to give the corresponding 3-pivaloylpyrrolo[1,2-a]quinoxaline-1,2,4 (5H)-triones. Reactions of the latter with o-phenylenediamine led to the formation of 3,3'-(3,3-dimethyl-2-oxobutane-1,1-diyl)di[quinoxalin-2(1H)-ones].
