用Aufbau方法描述手性四面体分子
Description of chiral tetrahedral molecules via an Aufbau approach
摘要:
我们提出了一个预测建立的四面体分子,基于先前推导的手性指数,其特征在于四面体分子,与n个手性中心,作为非手性,非对映异构体,或对映异构体的功能,所观察到的反转(每个中心最多一个)下旋转和叠加到其镜像。所确定的规则集允许通过确定相对于所添加的中心的选择规则来对通过添加另一个手性中心获得的新分子进行分类。
英文摘要:
We propose a predictive building-up of tetrahedral molecules, based on a previously derived chirality index, which characterizes a tetrahedral molecule, with n chiral centers, as achiral, diastereoisomer, or enantiomer as a function of the observed inversions (at most one for each center) under rotation and superimposition to its mirror immage. The set of rules which is identified allows the classification of the new molecule, obtained by the addition of another chiral center, by the determination of the selection rule with respect to the added center.
