of chiral analytes, the urea and amide derivatives of α‐phenylethylamine, were prepared. The effect of inter‐molecular hydrogen‐bonding interaction on self‐discrimination of the enantiomers of analytes has been investigated using high‐resolution 1H NMR. It was found that the urea derivatives with double‐hydrogen‐bonding interaction exhibit not only the stronger hydrogen‐bonding interaction but also better
制备了两种手性分析物,即 α-苯乙胺的尿素和酰胺衍生物。已使用高分辨率 1H NMR 研究了分子间氢键相互作用对分析物对映体自识别的影响。发现具有双氢键相互作用的脲衍生物不仅表现出更强的氢键相互作用,而且比酰胺衍生物(除了带有两个 NO2 基团的衍生物)具有更好的自识别能力。目前的结果表明,双氢键相互作用促进了手性化合物的自识别能力。版权所有 © 2009 John Wiley & Sons, Ltd.
