Ethyl S-4-chloro-3-hydroxybutyrate Chemical Properties,Usage,Production

Chemical Properties

Colorless to light yellow liqui

Uses

Atorvastatin Intermediate

Uses

Ethyl (S)-(?)-4-chloro-3-hydroxybutyrate can be used as a starting material in the synthesis of 4-amino-3-hydroxybutyric acid, a compound of pharmacological importance.

Biosynthesis

Bioreductions catalyzed by alcohol dehydrogenases (ADHs) play an essential role in synthesizing chiral alcohols. A novel ADH, SmADH31, obtained from the Stenotrophomonas maltophilia genome, which can tolerate extremely high concentrations (6 M) of both substrate and product. The coexpression of SmADH31 and glucose dehydrogenase from Bacillus subtilis in Escherichia coli meant that as much as 660 g L–1 (4.0 M) ethyl 4-chloroacetoacetate was completely converted into ethyl (S)-4-chloro-3-hydroxybutyrate [(S)-CHBE] in a monophasic aqueous system with a >99.9% ee value and a high space-time yield (2664 g L–1 d–1). In the 100 ml-scale monophasic aqueous system (in triplicate), 66.0 g COBE (single batch charge) can be completely converted to (S)-CHBE (ee >99.9%) in only 6 h with 2 g of the SmADH31/GDH co-expressing cells. After extraction and evaporation, 61.6 g (S)-CHBE was isolated with 92% yield[1].

General Description

Ethyl (S)-4-chloro-3-hydroxybutanoate is a chiral intermediate generally used to prepare atorvastatin, a cholesterol-lowering drug.
