Abstract :5,5-Bis(methoxycarbonyl)-5,6-dihydro-3,7-diaryl-4H-1,2-diazepines (6) were prepared by the condensation of α-bromoacetophenone azines with dimethyl malonate in the presence of sodium methoxide. Halogenation of 6 afforded 7,7-bis(methoxycarbonyl)-2,5-diaryl-3,4-diazanorcaradienes (10) in excellent yields.
