SYNTHESIS OF ETRAHYDRO-1H-NAPHTH[1,2-D]-IMIDAZOLE-2,4,5-TRIONES AND TETRAHYDRO-1H-NAPHTH[2,3-D]IMIDAZOLE-2,4,9-TRIONES

Tricyclic compounds with an imidazolinone ring fused to 1,2- and 1,4-n aphtoquinones were synthesized by a reaction of 4-amino-1,2-naphthoqui none and 2-amino-1,4-naphthoquinone with electrophilic symmetric and n on symmetric diazenes.
