  Resolution of 2-aryloxy-1-propanols via lipase-catalyzed enantioselective acylation in organic media

  摘要：

  2-Aryloxy-1-propanols, primary alcohols with an oxygyen atom at the stereocenter. were resolved with good to high enantioselectivity by acylation with vinyl butanoate mediated by Pseudomonas sp. lipase in di-iso-propyl ether. Potential factors affecting the enantioselectivity of the enzymatic acylation were examined: solvents. acyl donors mid temperature, Using this enantioselective acylation procedure. enantiomeriocally pure (R)-2-(4-chlorophenoxy)-1-propanol was prepared on a grain scale.

• Microbial reduction and resolution of herbicidal 2-alkyl-2-aryloxyacetic acids by Gloeosporium olivarum.

  When a mold, Gloeosporium olivarum, was fermented with (±)-2-alkyl-2-aryloxyacetic acids (1-8), an enantioselective microbial reduction as well as microbial resolution took place, giving rise to (S)-2-alkyl-2-aryloxyethanols (1a-8a) and (R)-2-alkyl-2-aryloxyacetic acids (1b-8b). The configurations of the chiral 2-alkyl-2-aryloxyethanols and 2-alkyl-2-aryloxyacetic acids were consistent with those of the corresponding products formed by Glomerella cingulata, with the sole exception of 8b. The (R)-(+)-α-methoxy-α-trifluoromethylphenylacetic acid (MTPA) esters of the (S)-2-alkyl-2-aryloxyethanols showed larger lanthanide-induced shifts for the methoxy groups (1a, 4a-8a) or an aromatic proton (2a) in the nuclear magnetic resonance (NMR) spectra than the esters of the corresponding (R)-2-alkyl-2-aryloxyethanols. This result can be applied generally for the determination of the absolute configuration of 2-alkyl-2-aryloxyethanols.

  当霉菌Gloeosporium olivarum与(±)-2-烷基-2-芳氧乙酸（1-8）发酵时，发生了选择性的微生物还原和微生物分解，产生了(S)-2-烷基-2-芳氧乙醇（1a-8a）和(R)-2-烷基-2-芳氧乙酸（1b-8b）。手性2-烷基-2-芳氧乙醇和2-烷基-2-芳氧乙酸的构型与由Glomerella cingulata生成的相应产物相一致，唯一的例外是8b。 (R)-(+)-α-甲氧基-α-三氟甲基苯乙酸（MTPA）酯与(S)-2-烷基-2-芳氧乙醇在核磁共振（NMR）谱中显示出比相应的(R)-2-烷基-2-芳氧乙醇的酯对甲氧基（1a, 4a-8a）或芳香质子（2a）具有更大的镧系元素诱导位移。这一结果可普遍应用于确定2-烷基-2-芳氧乙醇的绝对构型。
