A novel synthetic route was developed for the construction of a chiral cis-hexahydro-γ-carboline derivative through Ir/ZhaoPhos-catalyzed asymmetric hydrogenation of corresponding tetrahydro-γ-carboline with high yields (up to 99% yield), excellent diastereoselectivities (up to >99 : 1 dr) and enantioselectivities (up to 99% ee), and high substrate-to-catalyst ratios (up to 5000).
开发了一种新的合成路线,用于通过 Ir/ZhaoPhos 催化相应四氢-γ-咔啉的不对称氢化构建手性顺式-六氢-γ-咔啉衍
生物,收率高(收率高达 99%),具有优异的非对映选择性(高达至 >99 : 1 dr)和对映选择性(高达 99% ee),以及高底物催化剂比(高达 5000)。
