| Abstract: | This paper reports a new method for synthesizing heterocycle - fused troponoid compounds by oxidizing azo - coupling products of 3 - isopropenyltropolone and 3 - cinnamoyltropolone with bromine in the presence of pyridine. Reactions of azo - couping products of 3 - isopropenyltropolone (1a -1f) and 3 - cinnamoyltropolone(3a - 3d)with excess bromine afford 5 - substitutedphenylazo - 7 -bromo - 3 - methyl - 8 - hydrocyclohepta [b] furan - 8 - one(2a - 2f) , 6 - substituted phenylazo - 2 -phenyl - 8 - bromo - 4,9 - dihydrohepta [b] pyran - 4,9 - dione(4a - 4d) respectively. |
