  Absolute configurations of monoesters produced by enzyme catalyzed hydrolysis of diethyl 3-hydroxyglutarate

  摘要：

  Biocatalytic asyminetrizations of diethyl 3-hydroxyglutarate furnish a route to the enantiomers of ethyl 4-cyano-3-hydroxybutanoate. The enantiopreference of different enzymes has been established by chiral chromatography. Conclusive evidence for absolute configurations has been provided by X-ray crystallographic structure determination of co-crystals of the predominant monoester with (R)-phenylethylamine. The predominant enantiopure monoester produced by ammonolysis of diethyl 3-hydroxyglutarate catalyzed by immobilized lipase B from Candida antarctica (Novozym 435) was ethyl (3S)-4-carbamoyl-3-hydroxybutanoate. This was converted to ethyl (3S)-4-cyano-3-hydroxybutanoate in high yield and enantiomeric excess. Growing cells of Acinetohacter lwoffii gave low ee and predominance of the (S)-enantiomer when used for hydrolysis of diethyl 3-hydroxyglutarate as opposed to previous reports. When Novozyni 435 was used for hydrolysis it could be re-used 10 times without loss of activity and selectivity. (C) 2004 Published by Elsevier Ltd.
