三烷基硼烷能与4-(二甲基硫叶立德)巴豆酸乙酯反应,给出(E/Z)-β,γ-不饱和酯(E:Z≈58:42),条件温和,产率高.该反应是一条使烷基延长四个碳原子得到β,γ-不饱和酯的新路线。
The trialkylborane can be reacted with 4- (dimethylthiolide) ethyl crotonate to give (E / Z) -β, γ-unsaturated ester (E: Z≈58: 42) The yield is high The reaction is a new route to extend the alkyl group by four carbon atoms to give the β, γ-unsaturated ester.
