controlling absolute stereochemical courses of general asymmetric induction events. Thus, a sensitive dependence of the sense of chiral induction on an alkene substrate’s substituent electronic polarizability character was uncovered from a range of structurally highly comparable Sharpless asymmetric dihydroxylation (AD) systems, from which a new polarizability-based stereochemical model of predictive power
柔软确实是力量!此处报道的是电子极化率(即柔软度)效应在控制一般不对称诱导事件的绝对立体化学过程中的关键但长期被忽视的作用。因此,从一系列结构上高度可比的Sharpless不对称二羟基化(AD)系统中发现了手性诱导感对烯烃底物的取代基电子极化率特征的敏感依赖性,从中提出了基于极化率的基于立体化学的新预测能力模型。
