A vast range of novel TADDOL-based diphosphite ligands were first synthesized and applied in the nickel-catalyzed asymmetric hydrocyanation of disubstituted methylenecyclopropanes. By employing these new catalysts, the conversion of diverse methylenecyclopropanes into their corresponding allylic nitriles was first enabled, in good yield with excellent enantioselectivities.
首先合成了大量新颖的基于TADDOL的二亚磷酸酯配体,并将其应用于镍催化的二取代的亚甲基环丙烷的不对称氢氰化反应中。通过使用这些新的催化剂,首先能够以良好的产率和优异的对映选择性将多种亚甲基环丙烷转化为其相应的烯丙基腈。
