Ethyl 4-Chloro-3-Hydroxybutanoate (CAS: 10488-69-4) is a key chiral intermediate in statins. For example, Ethyl 4-chloro-3-hydroxybutyrate is an intermediate of Olacetam, Olacetam in the treatment of alzheimer’s disease.

Ethyl 4-Chloro-3-Hydroxybutanoate (CAS: 10488-69-4), it is an important organic intermediate to synthesize precursor compounds of cholesterol-lowering drugs, but also for many activities synthesis of drugs such as hydroxymethylglutaryl reductase inhibitors and 1,4-dihydropyridine β-blockers. It has the advantage of being easy to synthesize and inexpensive, and it is a very cost-effective way to prepare Ethyll-4-Chloro-3-Hydroxy Butyrate by asymmetric reduction as a reaction raw material. Moreover, during the reaction, the microorganism does not use the product of the reaction to produce other new impurities, so that the preparation reaction can be carried out by using whole cells of the microorganism, and the reaction method is simpler. At present, there have been many reports on the preparation of chiral Ethyll-4-Chloro-3-Hydroxy Butyrate by asymmetric reduction of ethyl 4-chloroacetoacetate. The main preparation methods are chemical methods and biological methods. Among them, microbial catalysis in biological methods is a hot spot of research. Microbial catalysis utilizes the stereoselectivity of a specific microbial cell-specific enzyme system to selectively convert a substrate into a product in a cell. However, due to the complexity of the enzyme system present in the cell, the optical purity of the catalytic product is not high, and it is necessary to screen an excellent microbial strain or to improve by cloning a recombinant gene. Coenzyme addition is also required to provide the reducing power of the reaction.
