| Abstract: | We reported a new method for the fist time to synthesize Flavone like Heteroeycle fused Troponiid Compounds by oxidizing Azocoupling products of 3-cinnamoyltropolne with Bromine in the presence of pyridine. Reactions of Azo-couping products of 3-cinnamoyltropklone(la~d)with excess Brommine to afford 6-substitutedphenylazo-2 phenyl - 8 - bromine tropone b]pyran-4, 9-dione (2a~d ). Products 2a~d are four new compounds whose structures had confirmedby their elementary analysis and spectiumanalysis |
