We have demonstrated that a validated QSAR (quantitative structure–activity relationship) model can be constructed between sterimol steric parameters of the N-substituents of chiral 1,2-amino-phosphoramide ligands and the enantiomeric ratios of alcohol products produced in the asymmetric additions of diethylzinc to acetophenone, which is powerful for predicting the steric effects of ligand substituents
我们已经证明,可以在手性1,2-氨基磷酰胺配体的N-取代基的立体异构体空间参数与不对称加成中生成的醇产物的对映体比率之间建立一个经过验证的QSAR(定量结构-活性关系)模型。二乙基锌转化为苯乙酮,对预测配体取代基对对映体的空间效应有很强的作用,对优化配体具有指导意义。
