立体化学中的有关构型,特别是复杂化合物的构型以及反应后产物的构型确定,在短期内就得掌握或者很快完成反应方程式,对初学有机化学的学生来说,不是一件很容易的事。为了让学者在短期内学习简便、收效迅速、记忆扎实,笔者在多年来的教学过程中摸索出一点经验,运用乘法中正负号相乘时的变化规律:(+)·(+)=(+)、(+)·(-)=(-)或(-)·(+)=(-)、(-)·(-)+(-),来寻找所要确定化合物的构型与有关因素之间的关系,进而制定该化合物的构型。
The related stereochemistry, especially the configuration of the complex compound and the configuration of the product after the reaction, the reaction equation must be mastered or completed in a short period of time, which is not very good for beginner organic chemistry students Easy thing In order to make scholar learn in a short time is simple, effective, and solid memory, the author in the teaching process over the years to find out a little experience, the multiplication of the sign multiplied by the law of variation: (+) · (+) = ( (+) · (-) = (-) or (-) · (+) = (-), (-) · (-) + (-) to find the configuration and related factors of the compound to be identified The relationship between, and then formulate the configuration of the compound.
