对于含有手性碳原子化合物的构型命名方法,是基础有机化学教学中的一个重要内容.一九七○年以来,国内外教材中均采用了IUPAC所建议的R/S构型命名体系.一般来说,学生在掌握顺序规则和R/S命名原则方面并无困难.但是当随意写出二个化合物的Fischer投影式以后,如何能快速,准确地标出各个手性碳原子的R/S构型,或根据标明了R/S构型的命名名称,如何快速写出该分子的Fischer投影式,则就有困难了.本文总结出一种快速确定手性碳原子R/S构型命名方法,收到了良好的效果.
The nomenclature for the configuration of compounds containing chiral carbon atoms is an important part of basic organic chemistry teaching. Since 1970, the R / S configuration nomenclature suggested by IUPAC has been adopted in domestic and foreign teaching materials. In general, students have no difficulty in grasping the rules of order and R / S nomenclature, but how can you quickly and accurately identify the R / S of each chiral carbon atom when you write the Fischer projection of two compounds at random? Configuration, or according to the name of the R / S configuration, how to quickly write out the Fischer projection of the molecule is difficult.This paper summarizes a rapid determination of R / S configuration of chiral carbon atoms naming Method, received good results.
