摘要
报道了采用溴氧化3-异丙烯基(艹卓)酚酮和3-肉桂酰基(艹卓)酚酮合成杂环并(艹卓)酮化合物的新方法。3-异丙烯基(艹卓)酚酮5位偶联产物1a～1f和3-肉桂酰基(艹卓)酚酮5位偶联产物3a～3d分别在吡啶介质中与过量溴作用生成5-取代苯偶氮基-7-溴-3-甲基-8-氢环庚并呋喃-8-酮2a～2f和6-取代苯偶氮基-2-苯基-8-溴-4,9-二氢环庚并吡喃-4,9-二酮4a～4d。
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.
