asymmetric oxidation的用法详解

Asymmetric oxidation, also known as chiral oxidation, is a chemical reaction used to convert achiral molecules, or molecules without a mirror plane of symmetry, into molecules that contain separate enantiomerically pure forms. It is a type of asymmetric synthesis.

The most common type of asymmetric oxidation is the Sharpless asymmetric epoxidation, which uses a combination of titanium (IV) isopropoxide and an enzymatic hydroperoxide to convert an alkene into an epoxide. This reaction can provide high enantiomeric excess, with yields of up to 90%.

The Sharpless asymmetric dihydroxylation is another important asymmetric oxidation. This reaction uses a catalyst such as osmium tetroxide to convert an alkene into a 1,2-diol, which can then be further modified into other molecules. Other important types of asymmetric oxidation reactions include the Baeyer-Villiger oxidation, hydroformylation, and oxidations of cyano groups.

Asymmetric oxidations are widely used in the pharmaceutical and fine chemical industries to produce chiral and enantiomerically pure molecules. Asymmetric oxidations can also be used to synthesize natural products and complex target molecules, such as peptides, peptidomimetics, and terpenes.

In conclusion, asymmetric oxidation is an important class of reactions used to synthesize chiral compounds, and can be used to produce enantiomerically pure forms of molecules. These types of reactions are widely used in the pharmaceutical and fine chemical industries to produce molecules with desired properties.
