基于权原子和,提出了镶嵌在二维空间的苯环型化合物的手性程度,其中权原子和为与原子间的距离有关的原子不对称环境描述.在描述化合物的手性时,并没有采用简单的标记-手性或非手性,而是采用定量的方式来表征化合物的手性程度.定量手性程度能够区分对映体,并且一对对映体的手性程度为相反数.手性程度不仅仅可以采用单值,还可以采用多维向量来表示.此外,还将手性程度推广到三维正烷烃的旋转构象异构体描述,即首先将正烷烃的旋转异构体转化为苯环型化合物,然后采用手性程度描述其三维构象.
Based on the weighted sum of atoms, the degree of chirality of benzene ring compounds embedded in two-dimensional space is proposed, in which the right atom and the atom asymmetric environment are related to the distance between atoms. In describing the chirality of a compound, Rather than using simple labeling - chiral or achiral - quantitatively characterizing the degree of chirality of a compound, the degree of chirality quantifies the enantiomer and the degree of chirality of a pair of enantiomers is the opposite. The degree of chirality can be represented not only by single values but also by multidimensional vectors.In addition, the degree of chirality is extended to the description of the rotational conformational isomer of a three-dimensional n-alkane, that is, the rotational isomer of n-alkane is first converted into Benzene ring compounds, and then use the degree of chirality to describe the three-dimensional conformation.
