different anion (acetate, benzoate, fluoride, and chloride) have been studied by 1H‐NMR titration and have been observed in the case of 4 is a selective receptor for acetate. The theoretical calculation M06/6‐311+G(d,p) helped us explain the binding properties observed. The most interesting observation is that this calculated structure is consistent with expected, based on the concept of allylic 1,3‐strain
手性脲的新家族的合成有效,简单协议1 - 4进行说明。的结合性质1 - 4朝向不同阴离子(醋酸盐,苯甲酸盐,氟化物和氯化物)已经研究了通过1 H-NMR和滴定中的情况下,已经观察到4是用于醋酸选择性受体。理论计算M06 / 6-311 + G(d,p)帮助我们解释了观察到的结合特性。最有趣的观察结果是,基于烯丙基1,3-菌株(A 1,3菌株)的概念,该计算结构与预期一致。当研究手性丁二酸酯时,尿素1 是区分对映体的最佳方法。
