The enantioselective intra- and intermolecular [2 + 2] photocycloaddition of quinolone using a -symmetric chiral phosphoric acid as a visible-light photocatalyst is developed. The thioxanthone chromophore on phosphoric acid plays an important role in both phototransformation and enantioselectivity.
发展了一种使用 - 对称手性磷酸作为可见光光催化剂的喹诺酮的对映选择性的分子内和分子间 [2 + 2] 光环加成反应。在磷酸上的噻吨酮生色团在光转化和对映选择性中都起着重要作用。
