from carboxylic acid has been accomplished whereby the chemical scope of the tricyclodecadienone system as a synthetic equivalent of cyclopentadienone has been expanded. Bridgehead bromide gives upon treatment with base access to norbornene annulated cyclopentadienone which rapidly undergoes either regioselective nucleophilic addition or Diels-Alder cyclization depending on the applied reaction conditions
从羧酸开始有效合成6-官能化的内-三环[5.2.1.0 2,6 ] deca-4,8-dien-3-ones ,由此三环癸二烯酮系统的化学范围为环戊二烯酮的合成等价物已经扩展了。桥头溴化物可以通过降冰片烯环化的环戊二烯酮的碱处理而获得,根据所应用的反应条件,该环戊二烯酮可以快速进行区域选择性亲核加成或Diels-Alder环化。
