Angew.Chem.Int.Ed.2014,53,4648~4651螺烯作为一类具有独特螺旋手性的多环芳烃,不仅在光电材料等领域显示广泛的用途,而且在不对称催化中也具有重要的应用前景.然而,受到螺烯合成方法的局限,尤其是光活性且具有特殊官能团螺烯分子的合成挑战,极大地限制了螺烯作为一类新型的手性骨架在不对称催化、手性识别等领域中的应用.此外,由于螺烯本身的螺距较 Angew.Chem.Int.Ed.2014,53,4648 ~ 4651 As a class of polycyclic aromatic hydrocarbons with unique helical chirality, helium has been shown not only to be of widespread use in fields such as optoelectronic materials but also to be important in asymmetric catalysis However, due to the limitation of the method of synthesis of pyrene, especially the synthesis of photo-activated spiro-ene with special functional groups, the synthesis of pyrene has been greatly restricted. As a new type of chiral skeleton, Identification and other fields.In addition, due to the screw thread pitch itself
