Two amphiphilic chiral receptors 2a and 2b were designed and synthesized. Both are efficient chiral solvating agents for chiral carboxylic acids. In particular, 2a is an excellent CSA not only for lipophilic guests, but also for some hydrophilic guests. It is the first CSA for the direct determination of the enantiomeric composition of hydrophilic chiral hydroxylated acid in protic polar solvent.
设计并合成了两个两亲性手性受体2a和2b。两者都是用于手性羧酸的有效手性溶剂化剂。特别是2a不仅对亲脂性客人,而且对某些亲水性客人来说都是出色的CSA。这是第一个直接测定质子极性溶剂中亲水性手性羟基化酸的对映体组成的CSA。
