Folding of Long-Chain Alkanediammonium Ions Promoted by a Cucurbituril Derivative

We report the isolation and characterization of two top−bottom differentiated CB[n]-type receptors, namely ns-CB[6] and cucurbituril derivative 2, which display diastereoselective recognition toward unsymmetrical guests. Compound 2 also promotes the back-folding of long chain alkanediammonium ions in water.

本研究报告了两种顶底分化的CB[n]-型受体的分离与表征，分别为ns-CB[6]和葫芦脲衍生物2，它们对非对称性客体表现出对映选择性识别。化合物2还促进了长链烷基铵离子在水中的反向折叠。
