为了方便学员自学,本文按教材的章节顺序提出学习要求,并对学习中的重点、难点及易混淆的问题作如下讨论。 (一)立体化学 1.立体化学基础 ①复习对映异构与分子结构的关系。②掌握含手性碳原子化合物的对映异构现象。③掌握丙二烯型和联苯型的不含手性碳原子化合物的对映异构现象。 2.构象和构象分析 ①了解链状化合物
In order to facilitate learners to learn by themselves, this paper presents the learning requirements according to the chapters of the textbooks, and discusses the key points, difficulties and confusions in the study as follows. (A) Stereochemistry 1. Stereochemistry (1) review the relationship between enantiomeric and molecular structure. ② grasp the enantiomeric compounds containing chiral carbon atoms. ③ grasping propadiene and biphenyl-type chiral carbon atoms without enantiomeric compounds. 2. Conformation and conformation analysis ① understand the chain compound
