The supramolecular strategy was subjected to the asymmetric hydrogenation of 4-methylumbelliferone by electrochemical reduction in the presence of a chiral macrocyclic multifarane[3,3], which offered a l-7-hydroxy-4-methylchroman-2-one product with a chemical yield of 65% and enantioselectivity up to >99% ee. The high stability of the developed chiral supramolecular electrode guaranteed the recyclability
超分子策略是在手性大环 multifarane[3,3] 存在下通过电化学还原对 4-甲基伞形酮进行不对称氢化,得到 l -7- hydroxy -4-methylchroman-2-one 产物与化学反应产率为 65%,对映选择性高达 >99% ee。开发的手性超分子电极的高稳定性保证了电解中的可回收性和可重复性,因此,应用扩展到更多的香豆素衍生物,以提供令人满意的化学收率和对映选择性。
