  Lipase-catalyzed enantiomer selective hydrolysis of 1,2-diol diacetates

  摘要：

  Enantiomer selective hydrolysis of racemic 1,2-diol diacetates (rac-2a-h) was investigated by using the inexpensive commercial porcine pancreatic lipase. The hydrolysis proceeds with variable regioselectivity but with moderate to good enantioselectively yielding a mixture of isomeric monoacetates (3a-h and 4a-h) and unchanged diacetate enantiomers (2a-h). Evidence was found that both monoacetates (3a-h and 4a-h) are formed with the same sense of enantiomer selectivity.

• Aerobic Oxidation of Alkenes to Esters of Vicinal Diols with a<i>syn</i>-Configuration Catalyzed by I₂and the H₅PV₂Mo₁₀O₄₀Polyoxometalate

  A new method for the synthesis of vicinal diols from alkenes has been developed. Reaction of molecular iodine in the presence of a polyoxometalate as oxidation catalyst under aerobic conditions in acetic acid solvent leads to the oxidative iodoacetoxylation of an alkene, i.e. formation of a 1,2-iodoacetate. Further in situ substitution of the iodide by water yields the 1,2-diol monoacetate with a predominantly

  开发了一种从烯烃合成邻二醇的新方法。在作为氧化催化剂的多金属氧酸盐存在下，在有氧条件下，在乙酸溶剂中分子碘的反应导致烯烃的氧化碘乙酰氧基化，即形成1,2-碘乙酸盐。碘化物进一步被水原位取代产生具有主要（约4.5:1）顺式构型的1,2-二醇单乙酸酯。在反应的酸性条件下进一步酯化也会生成顺式二乙酸酯。该方法对于不使用有毒锇催化剂合成顺式邻位二醇可能是有价值的。
• Kinetic resolution of 2-acylated-1,2-diols by lipase-catalyzed enantiomer selective acylation

  Enantiomer selectivity of lipase catalyzed acylation of 2-acylated 1,2-diols was studied. First, acylation of 2-acetoxyheptan-1-ol rac-3b with vinyl acetate was investigated by varying the enzyme and the solvent, showing the highest enantiomer selectivity by using lipase from Pseudomonas fluorescens (PfL) in hexane-vinyl acetate (VA). We have found varying or even reversed enantiomer selectivity for different secondary acyl moieties in 2-acyloxyheptan-1-ols rac-3bA-F. Next, all six possible types of enantiomer selective biotransformations (hydrolysis of diacetate and the two kinds of monoacetetes; acylation of diol and the two kinds of monoacetates) were compared on two model diols rac-4b,d. Among the transformations investigated, acetylation of secondary monoacetates rac-3b,d showed the highest enantiomer selectivity. Finally, PfL catalyzed acetylations of several 2-acetylated 1,2-diols rac-3a-g were investigated under our optimum conditions. Copyright (C) 1996 Elsevier Science Ltd
