was designed and synthetized for overcoming these limitations at a molecular level. It is demonstrated, that this selector molecule is able to distinguish protonated primary, secondary and tertiary amines by the formation of reversible complexes with different stabilities. This degree of substitution-specific molecular recognition of amines opens the door to develop separation processes primarily focusing
大量的生物活性化合物含有至少一个胺官能团。适当的选择性只能在少数情况下通过取代这些基团来实现,因此胺的官能化通常会导致它们的混合物。这些具有非常相似特征的衍生物的分离只能在制备规模或通过应用预先优化的 HPLC 方法进行。为了在分子水平上克服这些限制,设计和合成了一种三(吡啶)冠醚。已经证明,该选择分子能够通过形成具有不同稳定性的可逆络合物来区分质子化的伯胺、仲胺和叔胺。
