the respective homochiral α-amino alcohols. The absolute configuration at the created stereogenic centre was assigned by CD spectra and by X-ray analysis. Conformational analysis of the title compounds was carried out using quantum chemical energy-geometry optimization. Thus established conformational behavior explained the strongly configuration dependent NMR spectral patterns observed for the u and
对映体纯ù和升β
氨基亚砜已被容易地从相应的纯手性α-
氨基醇得到。通过CD光谱和X射线分析确定在创建的立体成因中心的绝对构型。使用量子
化学能量几何优化对标题化合物进行构象分析。因此,确定的构象行为解释了对于u和l非对映异构体观察到的强烈依赖构型的NMR光谱图。
