摘要
本文合成了20个题示的化合物,研究了它们的~1H和^(31)P谱,找出了δp与取代基关系的一些规律,观察到了手性中心对δ_H的影响、及一个手性中心对另一个手性中心R、S体不等价的诱导位移,并观察了产物中R、S体的不同含量比例。
Twenty compounds of thiophosphate and thiophosphoramide containing α-cyno - m - phenoxy benzyl group were synthesized and their 1H and 31P NMR were determined . It was found that there were some relationships between δP and the substituted groups. The 1H spectra of these compounds were observed and discussed.
