isolation and conformational analysis of the diastereomeric 2-methylsulphinyl-1,2-diphenylethanol and of its O-methyl and O-acetyl derivatives are reported. Chemical correlations and the study of the influence of solvent polarity changes on the coupling constants have permitted the configurational assignment. Lanthanide shift reagents have been used also. to this effect. The role of hydrogen bonding in the
报道了非对映体2-甲基亚磺酰基-1,2-二苯乙醇及其O-甲基和O-乙酰基衍生物的合成,分离和构象分析。化学相关性和溶剂极性变化对偶合常数的影响的研究允许进行构型分配。也已经使用了镧系元素转移试剂。为此。氢键在羟基亚砜中的作用已在稀释溶液中通过IR和NMR光谱进行了评估。氧和硫之间的供体-受体相互作用已经被用来解释在硫原子上差向异构亚砜之间构象行为的差异。
