  Baker's yeast mediated reduction of dihydroxyacetone derivatives

  摘要：

  Several monoprotected dihydroxyacetone derivatives 4a-d and their acetates 5a-d were prepared and subjected to biotransformation with baker's yeast. The simple chemical modification of the substrates (i.e. transforming the relatively small hydrophilic hydroxymethyl group into a larger hydrophobic acetoxymethyl moiety) inverted the sense of enantiotope selectivity of these reductions yielding optically active diols 6a-d, or their enantiomeric acetates (7a-d) and diols (ent-6a-d), respectively.

  Microbial asymmetric reduction of α-hydroxyketones in the anti-Prelog selectivity

  摘要：

  Yamadazyma farinosa IFO 10896 was found to reduce alpha -hydroxyketones bearing a phenyl ring to give optically active diols with anti-Prelog selectivity. The distance between the carbonyl group and the phenyl ring was shown to have an interesting effect on the reactivity and selectivity of the enzyme system. (C) 2001 Elsevier Science Ltd.

  A number of 3-O-substituted 1,3-dihydroxypropan-2-ones have been synthesized in view of their potential use as prochiral precursors of optically active glycerols. Indeed, the oxo-ethers have been reduced to the corresponding 3-O-substituted glycerols via chiral Ru complexes derived from (S)-binap, ( =(−)-(S)-2,2′-bis(diphenylphosphino)-1,1′-binaphthalene) with enantiomeric excesses up to 93%. The steric

  The dynamic kinetic resolution of 6‐hydroxypyranones with enals or alkynals through an asymmetric redox esterification is catalyzed by a chiral N‐heterocyclic carbene. The resulting esters are obtained in good to high yields and with high levels of enantio‐ and diastereocontrol. The reaction products are further derivatized to obtain functionalized sugar derivatives and natural products.

  An efficient method for the enantioselective construction of tertiary vinylglycols through a palladium‐catalyzed asymmetric decarboxylative cycloaddition of vinylethylene carbonates with formaldehyde was developed. By using a palladium complex generated in situ from [Pd2(dba)3]⋅CHCl3 and a phosphoramidite ligand as a catalyst under mild reaction conditions, the process allows conversion of racemic

  The preparation of optically active 1,2-diols bearing a substituent with a benzyloxy group at the terminus has been achieved by microbial enantioselective oxidation of the racemic compounds. In the screening test, Ochrobactrum sp. MU2293 was selected as the best strain to perform the enantioselective oxidation of (±)-4-benzyloxybutane-1,2-diol to give the corresponding 4-benzyloxy-1-hydroxybutan-2-one and the remaining (R)-diol with a high ee. This microbial oxidation was applicable to other substrates bearing a substituent with a different carbon number. On the other hand, Bacillus sp. MU2289 catalyzed the oxidation of the 1,2-diols to afford the corresponding α-hydroxy ketones and the (S)-diols as the remaining substrates with the opposite absolute configuration

  通过对外消旋化合物进行微生物对映体选择性氧化，制备出了具有光学活性的 1,2-二醇，其末端含有一个苄氧基取代基。在筛选试验中，选择了 Ochrobactrum sp. MU2293 作为最佳菌株，对 (±)-4-benzyloxybutane-1,2-diol 进行对映选择性氧化，得到相应的 4-benzyloxy-1-hydroxybutan-2-one 和剩余的 (R)-diol 且ee值高。这种微生物氧化法适用于含有不同碳数取代基的其他底物。另一方面，芽孢杆菌 MU2289 可催化 1,2-二醇的氧化反应，生成相应的 α-羟基酮和 (S)- 二醇，作为绝对构型相反的剩余底物。
