Tartaric arid

The oxidation of phenol by means of potassium permanganate has been studied by Dobner.52 In as much as the product proved in this case to be meso-tartaric acid, it seems probable that hydroquinone, quinone and maleic arid may have been formed as intermediate products,08 particularly in view of the fact that the latter when oxidized with potassium permanganate is known to yield inactive tartaric arid.54...

Early in this chapter, we said that most of the molecules in nature are chiral, arid that Nature usually produces these molecules as single enantiomers. We ve talked about the amino acids, the sugars, ephedrine, pseudoephedrine, and tartaric acid—all compounds that can be isolated from natural sources as single enantiomers. On the other hand, in the lab, if we make chiral compounds from achiral starting materials, we are doomed to get racemic mixtures. So how do chemists ever isolate compounds as single enantiomers, other than by extracting them from natural sources We ll consider this question in much more detail in Chapter 45, but here we will look at the simplest way using nature s enantiomerically pure compounds to help us separate the components of a racemic mixture into its two enantiomers. This process is called resolution.
