  嗜热丝状真菌的新型水解酶用于对映体和对映体选择性生物转化

  摘要：

  在两种摇瓶培养基上培养了十四种嗜热丝状真菌，并使用橄榄油，对硝基苯基棕榈酸酯和对硝基苯基丁酸酯作为底物，测定上清液的脂肪酶/羧酸酯酶活性。粗酶粉（丙酮沉淀的上清液）在有机溶剂中作为生物催化剂进行了测试。外消旋1-苯基乙醇（rac - 1）的动力学拆分和2-酰氧基丙烷-1,3-二醇的不对称化（3a，b）通过用乙酸乙烯酯乙酰化选择）以测试这些制剂的生物催化能力。就对映体的选择性而言，经测试的生物催化剂被证明与市售酶相当，而与最常见的市售酶相比，它们表现出更广泛的对位选择性。

  Regio- and enantioselective esterifications of polyoxygenated compounds catalyzed by lipases

  摘要：

  The lipase catalyzed esterifications of derivatives of propane-1,2,3-triol and butane-1,2,4-triol in organic solvents have been studied. The influence of several factors (lipase source, organic solvent, additives and structural variations in die substrates) on the selectivity have been investigated. Good levels of regio- and enantioselectivity have been achieved, providing practical methods for the synthesis of these chiral building blocks.

• Efficient chemoenzymatic enantioselective synthesis of diacylglycerols (DAG)

  A new efficient chemoenzymatic methodology for the production of 3-O-benzyl-sn-glycerol and 1,2-O-dipalmitoyl-sn-glycerol has been developed. It starts from racemic 1-O-benzylglycerol and is based on the sequential enzymatic acylation-Mitsunobu inversion-enzymatic hydrolysis, which has been performed without isolation of the intermediates. In this way a 70-75% yield of 3-O-benzyl-sn-glycerol with 94-96% ee has been obtained. (C) 2004 Published by Elsevier Ltd.
• Baker's yeast mediated reduction of dihydroxyacetone derivatives

  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.
