通过动态动力学拆分途径,在市售手性二胺配体存在下,通过锡-锂交换从N-Boc-2-三丁基锡烷基吡咯烷或通过去质子化从N-Boc-吡咯烷衍生的有机锂发生不对称取代,具有高水平的对映选择性。
Asymmetric substitution of the organolithium derived either from N-Boc-2-tributylstannylpyrrolidine by tin-lithium exchange or from N-Boc-pyrrolidine by deprotonation occurs in the presence of a commercially available chiral diamine ligand with high levels of enantioselectivity by a dynamic kinetic resolution pathway.
