    摘要:
    3-和5-卤素取代的2(H)-吡喃-2-酮与富电子和缺电子的亲二烯体的狄尔斯-阿尔德反应可提供稳定且易于分离的桥连双环内酯环加合物。这些环加成反应具有优异的区域选择性和非常好的立体选择性。相反,4-卤代的2(H)-吡喃-2-酮的Diels-Alder反应提供的环加合物非常容易失去桥接CO 2并随后形成桶烯([2.2.2]环辛烯)。此外,这些环加成仅以适度的区域选择性和立体选择性进行。对于3-和5-卤代2(H)-吡喃-2-酮和4-卤代2(H)-吡喃-2-酮,卤素之间的反应模式没有明显变化。通过计算研究了卤素取代的2(H)-吡喃-2-酮的环加成的区域和立体化学偏好。通过使用密度泛函理论(B3LYP / 6-31G *)对导致四种可能的区域和立体异构环加合物的过渡态进行了计算。这些研究允许预测这些反应中的区域选择性和立体选择性,这与实验观察结果基本一致。
