在立体化学教学中,明确地描述一个化合物的构型十分重要。关于对映异构体构型的表示方法,见之于教材、文献且较为普遍应用的,有如F ischer投影式、透视式(伞形式、楔形式)和四面体式等。这些表示式,其各自所具有的特定含义,本来是众所周知、不必赘述的了,然而在比较各种教材、文献之后,发现它们在有些方面概念并不一致,在某些问题的讲法上尚有值得商榷之处。这种情况,有必要加以澄清,为此,本文拟就有关问题提出讨论。
In stereochemical teaching, it is important to clearly state the configuration of a compound. See the teaching materials, literature and more commonly used, as Fischer projection, perspective (umbrella form, wedge form) and tetrahedron, etc. on the representation of the enantiomeric configuration. These expressions have their own specific meaning, was well known, need not go into details, but after comparing various textbooks, literature, found that they are not consistent in some aspects of the concept, there are some problems on the way there is worthy of Discuss the place. This situation, it is necessary to clarify, to this end, the paper proposed to discuss the issue.
