  Significantly Improved Equilibrium Yield of Long-Chain Alkyl Glucosides via Reverse Hydrolysis in a Water-Poor System Using Cross-Linked Almond Meal as a Cheap and Robust Biocatalyst

  摘要：

  An array of ten beta-D-glueopyranosides with varied alkyl chain lengths were enzymatically synthesized. It was found that for longer alkyl chains a lower initial rate and final yield of glucoside was obtained except for methyl glucoside because of the severe toxicity of methanol to the enzyme. From a thermodynamics point of view, the equilibrium constant and Gibbs free energy variation of the glucoside syntheses were systematically investigated. To improve the final yields of the glucosides containing long alkyl chains the equilibrium of the enzymatic glucoside synthesis was altered. The equilibrium yield of decyl beta-D-glucoside increased from 1.9% to 6.1% when the water content was reduced from 10% to 5% (v/v) using tert-butanol as a cosolvent and 0.10 mol/L of glucose as a substrate. As for the other longer alkyl chain glucosides, heptyl beta-D-glucoside was found to have significant surface activity as well.

  Site-selective and product chemoselective aliphatic C–H bond oxidation of 1,2-diols and of polyhydroxylated substrates using iron and manganese catalysts and hydrogen peroxide as terminal oxidant is described. The reaction capitalizes on the use of fluorinated alcohol solvents such as 2,2,2-trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), which exert a strong polarity reversal in

  介绍了使用铁和锰催化剂以及过氧化氢作为末端氧化剂对1,2-二醇和多羟基化底物进行位点选择性和产物化学选择性的脂肪族CH键的氧化反应。该反应利用了氟化醇溶剂，例如2,2,2-三氟乙醇（TFE）和1,1,1,3,3,3,3-六氟-2-丙醇（HFIP），可产生强烈的极性反转1,2-二醇的羟基部分通过氢键结合，进而转化为针对HAT的近端C-H键的强烈失活，而HAT则通过假定的高价和亲电金属-氧代物质氧化。结果，描述了复杂的多官能分子（例如类固醇，糖和药物）的位点选择性氧化和产物化学选择性氧化，在偏远且未激活的位置发生独家或主要的C–H键羟化反应。本报告公开了在氟化醇溶剂中由HAT引发的羟基化反应，作为显示出对当代醇氧化具有正交化学选择性的方法，为在密集官能化分子中进行合成规划提供了有用的工具。

  日期：——

  Direct β-glucosidation between 1,6-octanediol (5) and D-glucose (3) using the immobilized β-glucosidase (EC 3.2.1.21) from almonds with the synthetic prepolymer ENTP-4000 gave a mono-β-glucoside (6) in 61.4% yield, which was converted into the n-hexyl β-D-glucopyranoside (1) by means of a chemoenzymatic method. The coupling of the n-hexyl β-D-glucopyranoside congener (13) and 2,3,4-tri-O-acetyl-β-D-xylosyl congener (14), followed by deprotection, afforded the synthetic n-hexyl O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside (2), which was identical to the natural 2 with respect to the spectral data and specific rotation.

  利用杏仁来源的固定化β-葡萄糖苷酶（EC 3.2.1.21）在合成预聚物ENTP-4000的辅助下，将1,6-辛二醇（5）与D-葡萄糖（3）直接进行β-葡萄糖苷化反应，以61.4%的产率得到了单-β-葡萄糖苷（6），再通过化学酶法将其转化为正己基β-D-吡喃葡萄糖苷（1）。接着，正己基β-D-吡喃葡萄糖苷类似物（13）与2,3,4-三-O-乙酰基-β-D-木糖苷类似物（14）进行偶联，随后去保护，合成了正己基O-β-D-木吡喃糖基-(1→6)-β-D-葡萄吡喃糖苷（2），该化合物在光谱数据和比旋光度上与天然产物2完全一致。
