WebDec 3, 2024 · Enantiomers always contain chiral centers. Enantiomers often display similar physical properties and chemical reactivities, although the molecules may be distinguished by how they polarize light. In biochemical reactions, enzymes usually react with one enantiomer in preference to the other. WebStereochemistry is an important issue in any synthesis. This chapter illustrates two key points. First, disconnection should be done at a C C bond where one of the carbon atoms is a stereogenic center. Disconnection of a bond away from the stereogenic center usually leads to a less efficient and less desirable retrosynthesis, and often more ...

WebAn atom with four different groups bonded to it in such a way that it has a non-superimposable mirror image is called a chiral center. A chiral molecule and its mirror image are as follows:- Chirality "The objects which are non-superimposable on their mirror image are said to be chiral and this property is known as chirality''. WebLet’s apply our general discussion to real molecules. For now, we will limit our discussion to molecules with a single chiral center. It turns out that tartaric acid, the subject of our chapter introduction, has two chiral centers, so we will come back to it later. Consider 2-butanol, drawn in two dimensions below.
