Abstract
A concise synthesis of cinchona-alkaloid-derived NN ligands bearing alkyl substituents on chiral nitrogen atoms was described. Iridium catalysts containing new chiral NN ligands and achiral phosphines were effective for the asymmetric hydrogenation of heteroaromatic ketones, which afforded corresponding alcohols in up to 99.9% ee. The same protocol was applicable to the asymmetric hydrogenation of α-chloroheteroaryl ketones. Most importantly, the gram-scale asymmetric hydrogenation of 2-acetylthiophene and 2-acetylfuran proceeded smoothly even under 1 MPa of H2.

Abstract
Fluoro‐substituted and heteroaromatic compounds are valuable intermediates for a variety of applications in pharma‐ and agrochemistry and synthetic chemistry. This study investigates the chemoenzymatic preparation of chiral alcohols bearing a heteroaromatic ring with an increasing degree of fluorination in α‐position. Starting from readily available picoline derivatives prochiral α‐halogenated acyl moieties were introduced with excellent selectivity and 64–95 % yield. The formed carbonyl group was subsequently reduced to the corresponding alcohols using the alcohol dehydrogenase from Lactobacillus kefir, yielding an enantiomeric excess of 95–>99 % and up to 98 % yield.

Abstract
(R)-3-Hydroxypentanenitrile (HPN) is an important intermediate in the synthesis of an immunosuppressive inosine 5′-monophosphate dehydrogenase inhibitor. An efficient enzymatic procedure for the synthesis of (R)-HPN with over 99 % enantiomeric excess using a novel acetoacetyl-CoA reductase (AdKR) from Achromobacter denitrificans was successfully established. Many microorganisms are known to reduce 3-oxopentannitrile (KPN) to (R)-HPN. An enzyme from A. denitrificans partially purified using ion exchange chromatography reduced KPN to (R)-HPN with high enantioselectivity. The AdKR gene was cloned and sequenced and found to comprise 738 bp and encode a polypeptide of 26,399 Da. The deduced amino acid sequence showed a high degree of similarity to those of other putative acetoacetyl-CoA reductases and putative 3-ketoacyl-ACP reductases. The AdKR gene was singly expressed and coexpressed together with a glucose dehydrogenase (GDH) as a coenzyme regenerator in Escherichia coli under the control of the lac promoter. (R)-HPN was synthesized with over 99 % e.e. using a cell-free extract of recombinant E. coli cells coexpressing AdKR and GDH.

Abstract
Enantioenriched heteroaryl ethanols and aryl heteroarylmethanols are important intermediates and structural motifs in medicinal chemistry. Asymmetric biocatalytic reduction of corresponding ketones provides a straightforward approach for preparation of these compounds. Accordingly, three newly isolated fungal strains have been described, which produced the desired heteroaryl alcohols in high enantiomeric excess (ee). A broad substrate specificity was observed within these limited number of biocatalysts as demonstrated by preparation of a variety of heteroaryl alcohols, including (S)-5-(1-hydroxyethyl)furo[2,3-c]pyridine, a key intermediate for HIV-1 reverse transcriptase inhibitor, (S)-phenyl(pyridin-2-yl)methanol, an analgesic and (S,S)-2,6-bis(1-hydroxyethyl)pyridine, a chiral building block, mostly in >99% ee and 80-92% yield. Micro-morphologically, one of the isolate was found to be similar to Penicillium funiculosum. However, its β-tubulin sequence showed only 88% sequence identity with the known β-tubulin sequences of Penicillium. It may, therefore, represent a new species of Penicillium. The other biocatalysts were identified as Alternaria alternata and Talaromyces flavus.

Abstract
A novel (R)-specific alcohol dehydrogenase (AFPDH) produced by Candida maris IFO10003 was purified to homogeneity by ammonium sulfate fractionation, DEAE-Toyopearl, and Phenyl-Toyopearl, and characterized. The relative molecular mass of the native enzyme was found to be 59,900 by gel filtration, and that of the subunit was estimated to be 28,900 on SDS-polyacrylamide gel electrophoresis. These results suggest that the enzyme is a homodimer. It required NADH as a cofactor and reduced various kinds of carbonyl compounds, including ketones and aldehydes. AFPDH reduced acetylpyridine derivatives, β-keto esters, and some ketone compounds with high enantioselectivity. This is the first report of an NADH-dependent, highly enantioselective (R)-specific alcohol dehydrogenase isolated from a yeast. AFPDH is a very useful enzyme for the preparation of various kinds of chiral alcohols.
