摘要
本文介绍了一种有机立体化学的旋光异构体Ｒ／Ｓ构型命名标记的简易新方法。该法归纳为三步法：（１）切割和排序；（２）书写费歇尔投影式；（３）画圈，由轮转方向确定构型。该法不仅对开链状旋光化合物，特别对具有复杂结构的旋光化合物，如环状体系、扭转结构的螺环体系等旋光化合物的Ｒ／Ｓ构型标记是一种简易、快速和准确的命名方法。该法通过多年实践，取得了良好效果。
This paper introduces a simple process of naming and labelling the R/S configuration ofrotatory isomer in organic cubic chemistry. The method is induced as the one of three steps:①Cuttingand ordering;②Writing Fischer projection formula;③Drawing a circle and ascertaining configurationin terms of the direction of rotation.This process is suitable not only to ascertain open-chain rotatory compound but also to complicated rotatory compound,such as,cyclic system and R/S configurationmark of spifocyclic rotatory compound with twisted structure.Through Dractising for a number ofyears,this method is simple,quick and precise and a good effect in teaching has been received.
