WebDec 17, 2024 · A meso compound contains a plane of symmetry and so is achiral, regardless of whether the molecule has a chiral center. A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each other. By definition, a molecule that's not superimposable on its mirror image is a chiral molecule. 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 ...
