The 1H, 13C, and 15N NMR spectra of 5 exocyclic alkenes and 15 different ketimines obtained from cyclohexanone and derivatives using benzyl bromide and primary amines—are analyzed. Relative stereochemical and preferential conformations are determined by analyzing both the homonuclear coupling and the chemical shifts of the protons and carbon atoms in the aliphatic rings, which are directly related
分析了使用苄基溴和伯胺从环己酮和衍生物获得的 5 种环外烯烃和 15 种不同的酮亚胺的 1H、13C 和 15N NMR 光谱。相对立体化学和优先构象是通过分析脂族环中质子和碳原子的同核偶联和化学位移来确定的,这些化学位移与双键的几何形状以及外环基团的空间和电子效应直接相关。此外,N-(4-甲基亚环己基)吡啶-3-胺衍生物的外消旋混合物被拆分。版权所有 © 2008 John Wiley & Sons, Ltd.
