An effective synthesis of endo-6-bromo-tricyclo[5.2.1.02,6]deca-4,8-dien-3-one is realized starting from carboxylic acid applying Barton's halodecarboxylation methodology. Mild basic treatment of leads to quantitative formation of tricyclo[5.2.1.02,6]decatrienone which rapidly undergoes either regioselective nucleophilic addition or Diels-Alder cyclization depending on the applied reaction conditions
应用Barton的卤代羧化方法从羧酸开始,实现了对内-6-溴-三环[5.2.1.0 2,6 ] deca-4,8-dien-3-one的有效合成。温和的碱性处理导致定量形成三环[5.2.1.0 2,6 ]癸三烯酮,视所应用的反应条件而定,三环[5.2.1.0 2,6 ]癸三烯酮会迅速进行区域选择性亲核加成或Diels-Alder环化反应。
