Novel chiral receptors based on l-phenylalanine and l-valine have been synthesized and their chiral recognition properties toward mandelic acid and N-tosyl α-amino acids are studied. The phenylalanine-based receptor undergoes enantioselective gel formation with R-mandelic acid and N-tosyl-d-valine, whereas the valine-linked receptor in their presence results in the formation of precipitates.
合成了基于1-苯基丙氨酸和1-缬氨酸的新型手性受体,并研究了它们对扁桃酸和N-甲苯磺酰基α-氨基酸的手性识别特性。基于苯丙氨酸-受体经历对映选择性形成凝胶与[R -扁桃酸和Ñ甲苯磺酰d -缬氨酸,而在在沉淀物的形成它们的存在的结果缬氨酸-连接的受体。
