Quality Control of 2,4-Dichlorobenzoic acid. I found the field of Chemistry very interesting. Saw the article Ketoreductase catalyzed stereoselective bioreduction of alpha-nitro ketones published in 2019, Reprint Addresses Huang, ZD; Chen, F (corresponding author), Fudan Univ, Dept Chem, Engn Ctr Catalysis & Synth Chiral Mol, 220 Handan Rd, Shanghai 200433, Peoples R China.; Huang, ZD; Chen, F (corresponding author), Shanghai Engn Res Ctr Ind Asymmetr Catalysis Chir, 220 Handan Rd, Shanghai 200433, Peoples R China.. The CAS is 50-84-0. Through research, I have a further understanding and discovery of 2,4-Dichlorobenzoic acid.
We report here the stereoselective bioreduction of -nitro ketones catalyzed by ketoreductases (KREDs) with publicly known sequences. YGL039w and RasADH/SyADH were able to reduce 23 class I substrates (1-aryl-2-nitro-1-ethanone (1)) and ten class II substrates (1-aryloxy-3-nitro-2-propanone (4)) to furnish both enantiomers of the corresponding -nitro alcohols, with good-to-excellent conversions (up to >99%) and enantioselectivities (up to >99% ee) being achieved in most cases. To the best of our knowledge, KRED-mediated reduction of class II -nitro ketones (1-aryloxy-3-nitro-2-propanone (4)) is unprecedented. Select -nitro alcohols, including the synthetic intermediates of bioactive molecules (R)-tembamide, (S)-tembamide, (S)-moprolol, (S)-toliprolol and (S)-propanolol, were stereoselectively synthesized in preparative scale with 42% to 90% isolated yields, showcasing the practical potential of our developed system in organic synthesis. Finally, the advantage of using KREDs with known sequence was demonstrated by whole-cell catalysis, in which -nitro alcohol (R)-2k, the key synthetic intermediate of hypoglycemic natural product (R)-tembamide, was produced in a space-time yield of 178 g L-1 d(-1) as well as 95% ee by employing the whole cells of a recombinant E. coli strain coexpressing RasADH and glucose dehydrogenase as the biocatalyst.
