烯烃是一类含有C—C双键的烃类化合物，具有较高的反应活性和化学稳定性，在药物合成领域具有广泛的应用价值。例如，在青霉胺抗生素的合成中，烯烃是重要的中间体.

 Alder(-ene)烯反应，又叫作氢-烯丙基加成反应，是一个带有烯丙基氢的烯烃和一个亲烯体之间发生的反应。这个反应由Kurt Alder(阿尔德)和他的导师Otto Diels(狄尔斯)共同发现，在1950年他们二人因对双烯合成反应(Diels-Alder反应)的研究共享诺贝尔奖。这是一个官能团转化反应，包含有双键以及[1,5]氢迁移，产物是一个双键移动至原烯丙基位置的取代烯烃。烯反应是一种有用的形成C—C键的方法，用于合成复杂分子和天然产物。

  反应过程是亲烯体和烯丙基化合物的六中心σ键迁移。烯烃的π键、烯丙位的sp3-σC—H键都参与周环反应。在此过程中双键的迁移、新的C—H和C—C σ键的形成是同时进行的。

   南开大学化学学院李鑫、程津培团队报道了在手性磷酸和三(五氟苯基)硼(B(C6F5)3/CPA)催化下，2-芳基-3H-吲哚酮为亲烯体，α-甲基苯乙烯为烯烃的首例无金属催化的酮亚胺不对称ene反应。
