The synthesis and conformational analysis of some thioderivatives But-CHX-CH2Y (X = OH and OAc: Y = SH, SMe, SO2Me and SMe2) are reported. The conformational equilibra have been established from IH-NMR data and high dilution ir studies. All the compounds exhibited almost monoconformational behaviour around the C(1)-C(2) bond, due to strong steric factors. The observed vicinal coupling constants were
报道了一些硫代衍生物But-CHX-CH 2 Y(X = OH和OAc:Y = SH,SMe,SO 2 Me和SMe 2)的合成和构象分析。构象平衡已根据IH-NMR数据和高稀释度的ir研究确定。由于强的空间因素,所有化合物都在C(1)-C(2)键周围表现出几乎单构象的行为。观察到的邻位偶合常数用于检查具有不同氧化态的硫的化合物的Altona方程的不同参数化。还评估了可能的二面角变形。
