A supramolecular chiral host consisting of N-(2-naphthoyl)-L-aspartic acid (L-1) and meso-1,2-diphenylethylenediamine (2) is effective in enantioseparation of 1-arylethanols (up to 96% ee with 100% inclusion ratio). Here we report three different methods to prepare the inclusion crystals and discuss the chiral recognition mechanism on the basis of X-ray crystallography results.
由 N-(2-萘甲酰基)-L-天冬氨酸(L-1)和介-1,2-二苯基乙二胺(2)组成的超分子手性宿主可有效地对 1-芳基乙醇进行对映体分离(在包合率为 100%的情况下,ee 值高达 96%)。在此,我们报告了制备包合物晶体的三种不同方法,并在 X 射线晶体学结果的基础上讨论了手性识别机制。
