The present invention relates to a composition having the general formula: ##STR1## wherein each of A, B, C, X, Y, and Z is independently O, NH, N(CH.sub.2).sub.m CH.sub.3 ], N(C.dbd.O) (CH.sub.2).sub.m CH.sub.3 ], CH.sub.2, S, or Se; each of R.sub.1, R.sub.2, and R.sub.3 is independently phenyl, 4-hydroxyphenyl, pyridyl, pyrrolyl, indolyl, naphthyl, thiophenyl, (C.dbd.O) (CH.sub.2).sub.p CH.sub.3, NH(C.dbd.O) (CH.sub.2).sub.p CH.sub.3 ], OH, COOH, NH.sub.2, or SH; and m, n, and p are integers between 0 and 5. The composition is a chiral receptor molecule useful for the purification of enantiomers of derivatives of amino acids and of compounds able to form hydrogen bonds. The preparation of the composition involves coupling a trifunctional aromatic molecule with three protected chiral molecules at the three aromatic groups, cleaving protecting groups, and joining adjacent chiral groups by multiple lactamizations. The receptor may be used in a form either bound to a solid support or dissolved in an immiscible phase to effect convenient purification of enantiomers or other compounds of interest.
本发明涉及具有通用公式的组合物:##STR1## 其中A、B、C、X、Y和Z中的每个都独立地是O、NH、N(CH.sub.2).sub.m CH.sub.3]、N(C.dbd.O)(CH.sub.2).sub.m CH.sub.3]、CH.sub.2、S或Se;R.sub.1、R.sub.2和R.sub.3中的每个都独立地是苯基、4-羟基苯基、吡啶基、吡咯基、吲哚基、萘基、噻吩基、(C.dbd.O)(CH.sub.2).sub.p CH.sub.3、NH(C.dbd.O)(CH.sub.2).sub.p CH.sub.3]、OH、COOH、NH.sub.2或SH;m、n和p是0到5之间的整数。该组合物是一种手性受体分子,可用于对氨基酸衍生物和能够形成氢键的化合物的对映体进行纯化。该组合物的制备涉及将一种三官能芳香分子与三种受保护的手性分子耦合在三个芳香基上,裂解保护基,并通过多重内酰胺化将相邻的手性基结合。该受体可以以绑定到固体支撑物或溶解在不相容相中的形式使用,以便方便地纯化对映体或其他感兴趣的化合物。
