  串联酸/碱催化方法合成不对称甘油二醚的简便可扩展方法学

  摘要：

  已经设计了一种有用的优化合成方法，用于从表氯醇合成非对称甘油二醚。将廉价，多相且可完全回收的酸催化剂与碱性氢氧化物结合使用的串联方法可用于合成多种甘油衍生的醚，这些醚在1和3位带有不同的烷基取代基。对于表氯醇与几种醇的反应，已经测试了不同的非均相酸催化剂，使用易于获得的可回收且廉价的蒙脱土K10和Nafion NR50可获得最佳结果。对于第二反应步骤，使用氢氧化钾。在所有情况下，都能在平稳的反应条件下获得所需的甘油二醚的良好收率，始终具有表氯醇的总转化率，而无需中间纯化。串联工艺的规模放大已经取得了良好的结果。

  Optimised N-acetyl-d-lactosamine synthesis using Thermus thermophilus β-galactosidase in bio-solvents

  摘要：

  Synthesis of N-acetyl-D-lactosamine (Gal-beta[1 -> 4]GlcNAc, LacNAc) catalyzed by beta-galactosidase from Thermus thermophilus (TTP0042) is affected by side reactions that give as result very low yields (about 20%) of LAcNAc when the reaction is performed in buffer. The process is improved (up to 91% of disaccharide yield) when the reaction takes place in the presence of solvents from biomass (bio-solvents) at 2.0 M concentration. Most of the solvents tested increased the LacNAc synthesis and reduced the undesired side reactions. In order to understand the possible effects of these solvents over the enzyme regioselectivity, we developed a conformational study of the enzyme structure in the presence of a selected bio-solvent by circular dichroism and fluorescence. According to this study, we were able to conclude that the presence of bio-solvents in the reaction media modifies the enzyme secondary and tertiary structure and this may be the cause of the regioselectivity changes observed in the trans-glycosylation reaction.
