Abstract
Ketoreductase from growing cells of Klebsiella pneumoniae (NBRC 3319) acts as an efficient reagent for converting racemic α-benzyl/cinnamyl substituted-β-ketoesters to the corresponding β-hydroxy esters with excellent yields and stereoselectivities (ee and de >99 %). The reactions described herein followed a biocatalytic dynamic kinetic reductive resolution (DKRR) pathway, which is reported for the first time with such substrates. It was found that the enzyme system can accept substituted mono-aryl rings with different electronic natures. In addition, it also accepts a substituted naphthyl ring and heteroaryl ring in the α-position of the parent β-ketoester. The synthesized enantiopure β-hydroxy esters were then synthetically manipulated to valuable tetrahydropyran building blocks.

Abstract
This study presents the bioreduction of six β-ketoesters by whole cells of Kluyveromyces marxianus and molecular investigation of a series of 13 β-ketoesters by hologram quantitative structure-activity relationship (HQSAR) in order to relate with conversion and enantiomeric excess of β-stereogenic-hydroxyesters obtained by the same methodology. Four of these were obtained as (R)-configuration and two (S)-configuration, among them four compounds exhibited >99% enantiomeric excess. The β-ketoesters series LUMO maps showed that the β-carbon of the ketoester scaffold are exposed to undergo nucleophilic attack, suggesting a more favorable β-carbon side to enzymatic reduction based on adopted molecular conformation at the reaction moment. The HQSAR method was performed on the β-ketoesters derivatives separating them into those provided predominantly (R)- or (S)-β-hydroxyesters. The HQSAR models for both (R)- and (S)-configuration showed high predictive capacity. The HQSAR contribution maps suggest the importance of β-ketoesters scaffold as well as the substituents attached therein to asymmetric reduction, showing a possible influence of the ester group carbonyl position on the molecular conformation in the enzyme catalytic site, exposing a β-carbon side to the bioconversion to (S)- and (R)-enantiomers.

Abstract
The development of new approaches to obtain optically pure β-hydroxy esters is an important area in synthetic organic chemistry since they are precursors of other high value compounds. Herein, the kinetic resolution of racemic β-hydroxy esters using a planar-chiral DMAP derivative catalyst is presented. Following this procedure, a range of aromatic β-hydroxy esters was obtained in excellent selectivities (up to s = 107) and high enantiomeric excess (up to 99% ee). Furthermore, the utility of the present method was demonstrated in the synthesis of (S)-3-hydroxy-N-methyl-3-phenylpropanamide, a key intermediate for bioactive molecules such as fluoxetine, tomoxetine or nisoxetine, in its enantiomerically pure form.

Abstract
Bioreduction of 1-phenyl-2-propanone to prepare (S)-1-phenyl-2-propanol, a useful pharmaceutical intermediate, was performed with growing cells of Rhodococcus erythropolis JX-021, giving 14 mM (1.9 g/L) product in 99% e.e. at 5 h in the catalysis of 15 mM substrate. The reduction stopped afterwards due to strong inhibition of substrate and formed product, a problem that is often encountered in biotransformation. While the substrate inhibition was solved by stepwise feeding, product inhibition was tackled by different methods: repeated removal of the product by centrifugation, by absorption with Amberlite XAD-7 resin, and by the use of dodecanol as the second phase gave the final product in 58, 68, and 61 mM in the catalysis of 80 mM substrate, respectively. The inhibition was caused by the partial permeabilization of cell membrane of R. erythropolis JX-021, and addition of NADPH or glucose 6-phosphate to such cell culture retained the reduction activity. Therefore, higher productivity in the reduction of 1 with resting cells of R. erythropolis JX-021 was achieved through cofactor regeneration and recycling by the addition of glucose and permeabilized cells of Bacillus subtilis BGSC 1A1 containing a glucose dehydrogenase, giving the product in 62 mM without addition of cofactor and 78 mM with the addition of 0.01 mM NADP(+) in the catalysis of 120 mM substrate. The product e.e. retained 99% during the process which showed industrial possibility.

Abstract
The ability of Escherichia coli to grow on a series of acetylated and glycosylated compounds has been investigated. It is surmised that E. coli maintains low levels of nonspecific esterase activity. This observation may have ramifications for previous reports that relied on nonspecific esterases from E. coli to genetically encode nonnatural amino acids. It had been reported that nonspecific esterases from E. coli deacetylate tri-acetyl O-linked glycosylated serine and threonine in vivo. The glycosylated amino acids were reported to have been genetically encoded into proteins in response to the amber stop codon. However, it is our contention that such amino acids are not utilized in this manner within E. coli. The current results report in vitro analysis of the original enzyme and an in vivo analysis of a glycosylated amino acid. It is concluded that the amber suppression method with nonnatural amino acids may require a caveat for use in certain instances.

Abstract
In this study, the production of enantiomerically pure (1R,4S,6S)-6-hydroxy-bicyclo[2.2.2]octane-2-one ((-)-2) through stereoselective bioreduction was used as a model reaction for the comparison of engineered Saccharomyces cerevisiae and engineered Escherichia coli as biocatalysts. For both microorganisms, over-expression of the gene encoding the NADPH-dependent aldo-keto reductase YPR1 resulted in high purity of the keto alcohol (-)-2 (>99% ee, 97-98% de). E. coli had three times higher initial reduction rate but S. cerevisiae continued the reduction reaction for a longer time period, thus reaching a higher conversion of the substrate (95%). S. cerevisiae was also more robust than E. coli, as demonstrated by higher viability during bioreduction. It was also investigated whether the NADPH regeneration rate was sufficient to supply the over-expressed reductase with NADPH. Five strains of each microorganism with varied carbon flux through the NADPH regenerating pentose phosphate pathway were genetically constructed and compared. S. cerevisiae required an increased NADPH regeneration rate to supply YPR1 with co-enzyme while the native NADPH regeneration rate was sufficient for E. coli.

Abstract
Pure chiral molecules are needed in the pharmaceutical and chemical industry as intermediates for the production of drugs or fine chemicals. Microorganisms represent an attractive alternative to chemical synthesis since they have the potential to generate single stereoisomers in high enantiomeric excess (ee). The baker's yeast Saccharomyces cerevisiae can notably reduce dicarbonyl compounds (in particular alpha- and beta-diketones and keto esters) to chiral alcohols with high ee. However, products are formed at a low rate. Moreover, large amounts of co-substrate are required for the regeneration of NADPH that is the preferred co-factor in almost all the known dicarbonyl reductions. Traditionally, better ee, reduction rate and product titre have been achieved via process engineering. The advent of recombinant DNA technology provides an alternative strategy to improve productivity and yield by strain engineering. This review discusses two aspects of strain engineering: (i) the generation of strains with higher reductase activity towards dicarbonyl compounds and (ii) the optimisation of co-substrate utilisation for NADPH cofactor regeneration.

Abstract
A series of chiral beta(3)-aminoxy acids or amides with various side chains have been synthesized via two different approaches. One is the Arndt-Eistert homologation approach, using chiral alpha-aminoxy acids as starting materials. The other approach, utilizing the enantioselective reduction of beta-keto esters catalyzed by baker's yeast or chiral Ru(II) complexes, produces chiral beta(3)-aminoxy acids with nonproteinaceous side chains. The oligomers of beta(3)-aminoxy acids can be readily prepared using EDCI/HOAt as the coupling reagent.

Abstract
Improved stereoselectivity in dehydrogenase-mediated reductions has been achieved by rationally designed gene overexpression and knockouts in Saccharomyces cerevisiae cells and by isolating and characterizing novel dehydrogenases from other organisms. Transaminases have been used to prepare unnatural amines and amino acids in good yields, particularly when the equilibria are shifted by selective product removal.

Abstract
To overcome the maximum 50% yield limitation of classical resolution methods, deracemization processes involving a racemization step (dynamic resolution) or a prochiral intermediate (stereoinversion) have been developed. The use of transition metal complexes as racemizing agents, in combination with an enzymatic reaction, has been successfully extended to the deracemization of a number of simple or functionalized sec-alcohols. A two-enzyme process has been also investigated for their sequential or simultaneous deracemization. Other prominent results arise from an (apparently general) oxidoreduction process catalyzed by a single whole-cell microorganism.

Abstract
Asymmetric ketone reductions remain the most popular application of baker's yeast (Saccharomyces cerevisiae) in organic synthesis and data from the genome sequencing project is beginning to have an impact on improving the stereoselectivities of these reactions, augmenting traditional approaches based on selective inhibition. In addition, the catalytic repertoire of yeast has been expanded to include chiral ketone oxidations by overexpression of a bacterial Baeyer-Villiger monooxygenase.
