implicated in theories of the origin of life. Herein, we consider mixtures of imines and we show that if such complex mixtures are also dynamic—that is, if their components equilibrate among themselves—then they can dramatically simplify in composition during the course of column chromatography. As they travel down the column, imines continuously trade their aldehyde and amine constituents, favoring the formation
复杂混合物各组分之间的吸附差异在分离,基于表面的传感和多相催化中均起作用,并且已被认为与生命起源有关。本文中,我们考虑了
亚胺的混合物,并且表明如果这种复杂的混合物也是动态的,也就是说,如果它们的成分彼此平衡,那么它们可以在柱色谱过程中极大地简化组成。
亚胺沿着色谱柱向下移动时,会不断地交换其醛和胺成分,从而有利于形成具有极端极性的分子,而以具有中等极性的物质为代价。重复应用此原理可将最多包含16个成员的
亚胺文库简化为4种主要产品。
