立体化学是现代有机化学的重要内容。部颁大纲规定,在基础有机中学习立体化学的任务是“初步掌握立体化学的基本知识和基本理论”。就其内容而论,重点是静态立体化学(即分子在基态时的立体异构现象),动态立体化学(即反应过程中,分子运动变化中的立体化学)仅是初窥门径。为了让学生明确学习立体化学的目的,我们举出一些生产和生活实例来说明旋光异构现象的普遍性,藉以说明没有立体化学也就没有有机化学的今天。立体化学的内容贯串有机化 Stereochemistry is an important part of modern organic chemistry. The ministry outlines that the task of learning stereochemistry in basic organics is to “preliminarily grasp the basic knowledge and basic theory of stereochemistry.” As far as its content is concerned, the focus is on static stereochemistry (ie, the stereoisomerism of the molecule in the ground state). Dynamic stereochemistry (ie, the stereochemistry in the movement of molecules during the reaction) is only the initial veil. In order to allow students to clearly learn the purpose of stereochemistry, we cited some examples of production and life to illustrate the universality of optical isomerism, so as to illustrate the absence of stereochemistry and the absence of organic chemistry today. The content of stereochemistry is organically organized
