AZIRIDINYL KETONES AND THEIR CYCLIC ANILS. 8. 1,2-DIARYL-1,1a-DIHYDROAZIRINO/1,2-a/QUINOXALINES FROM SUBSTITUTE o-PHENYLENEDIAMINES AND CHALCONE DIBROMIDES

The reaction of 4-R-substituted (R=Br, Cl, OC2H5, CN, NO2) 1,2-phenylenediamines with 1,3-diaryl-2,3-dibromo-1-propanones in the presence of triethylamine gave 1,2-diaryl-5-R-1,1a-dihydroazirino/1,2-a/quinoxalines, which undergo isomerization in an acidic
