Photolysis of 2-(4-alkyl(phenyl)piperazino)-3-amino-1,4-naphthoquinones affords 2-alkyl(phenyl)-1,2,3,4,12,12a-hexahydronaphtho[2',3':4,5]imidazo[1,2-a]pyrazine-6,11-diols which recyclize at elevated temperatures to yield 1,2,3,4-tetrahydro-13-alkyl(phenyl)-3,1-(iminoethano)benzo[g]quinoxaline-5,10-diols. The latter are oxidated with atmospheric oxygen to the corresponding diones. On the basis of deuterium exchange data a mechanism for the recyclization is proposed.
