Final Yield

The asymmetric reduction of ethyl 4-chloro-acetoacetate (CAAE) to ethyl (R)-4-chloro-3- hydroxybutanoate (R-CHBE) biocatalysed by the aldehyde reductase of Sporobolomyces salmonicolor expressed in E. coli M15 (pQE30-alr) in combination with regeneration of NADPH by the glucose dehydrogenase of Bacillus megaterium expressed in E. coli M15 (pQE30-gdh) was reported. The bioreduction was carried out in a two-phase reaction system with n-butyl acetate as an organic solvent. Bioconversion of 300 mmol CAAE with a final yield of 97.5 % and an enantiometric excess of 99 % was achieved without the addition of cofactor NADPH.

Lignin Model

Lignin depolymerization through an oxidation method could provide value-added products, but it is challenging in terms of recovering catalysts or separating products in time to avoid over-oxidation. In this study, a process of selectively oxidative degradation of lignin model compounds was operated in a two-phase reaction system. Lignin model compounds of 4-benzyloxyphenol (PBP) or guaiacylglycerol-β-guaiacyl ether (GGE) in a bottom phase of 1-butyl-3-methylimidazole chloride ([BMIM]Cl) ionic liquid were selectively oxidized by H2O2 in the presence of a solid acid (SO42-/Fe2O3-ZrO2), and the degradation products immediately diffused into the upper organic solvent phase (butyl acetate). In this kind of reaction system, the yield of the products was improved due to the prolonged life of ∙OH in ionic liquid, and the product selectivity was maintained due to the timely product separation, and the ionic liquid and the catalyst were easily recycled.
