Abstract:
Ethyl (R)-2-hydroxy-4-phenylbutyrate was prepared by enzyme resolution of racemic ethyl- 2-hydroxy-4-phenylbutyrate. The optimal resolution conditions were 0.074 mol/L ethyl-2-hydroxy-4-phenylbutyrate, 20 mg lipase AK in 2.0 ml ethenylethanoate, 30 0C, 100 rpm. Enantiomeric excess of ethyl (R)-2-hydroxy-4-phenylbutyrate was up to 99%. Kinetic resolution model of ethyl- 2-hydroxy-4-phenylbutyrate by lipase AK was described by double substrate ping-pong mechanism. Model data agreed well with experimental data.

Abstract:
Ethyl (R)-2-hydroxy-4-phenylbutyrate ((R)-HPBE) is used as an intermediate in the production of angiotensin converting enzyme (ACE) inhibitors for treating various medical conditions. The study used Stereospecific carbonyl reductase (KmCR) enzyme for the asymmetric synthesis of (R)-HPBE. The optimization process involved varying IPTG concentration, induction temperatures, and induction times to determine the optimal culture conditions for producing (R)-HPBE with increased yields. The most efficient culture conditions were determined as 0.2 mM IPTG concentration, 17 °C temperature, and 10 h

Abstract:
The use of baker’s yeast to reduce ethyl 2-oxo-4-phenylbutyrate (EOPB) in conventional biphasic systems is hindered by low productivities due to mass transfer resistance between the biocatalyst and the substrate partitioned into two different phases. To overcome the limitation, a new reaction-separation coupling process (RSCP) was configured in this study, based on the novel thermosensitive ionic liquids (ILs) with polyoxyethylene-tail. The solubility of ILs in common solvents was investigated to configure the unique thermosensitive ionic liquids–solvent biphasic system (TIBS) in which the red
