    摘要:
    据报道,使用商业 NADPH 依赖性酮还原酶 K234 和 2-丙醇作为 NADPH 再生的共底物,可有效生物催化还原二氟烷基酮以获得手性氟烷基仲醇。这种生物还原反应可应用于广泛的前手性氟酮,包括芳基二氟酮、脂肪族二氟酮和三氟苯乙酮,在高底物浓度(100 g L -1). 这些结果表明 K234 在工业生产有价值的手性氟代醇方面具有潜力。此外,该生物催化方案在不添加外部烟酰胺辅助因子的情况下也可以有效,这为酮还原酶 K234 在手性仲醇不对称合成中的进一步应用提供了有用的指导。

    Generation of Magnesium Pentafluoropropen-2-olate from Hexafluoroisopropanol and Synthesis of 2,2,4,4,4-Pentafluoro-3,3-dihydroxyketones
    摘要:
    2,2,4,4,4-Pentafluoro-3,3-dihydroxyketones are valuable precursors to difluoroenolates following fragmentation during the release of trifluoroacetate; however, there are few synthetic strategies to prepare this unique class of compound. We addressed this issue and report a mild, two-step synthesis of 2,2,4,4,4-pentafluoro-3,3-dihydroxyketones from aldehydes. Specifically, aldehydes are treated with pentafluoropropen-2-olate, generated from a new fragmentation of hexafluoroisopropanol with a mixed Mg/Li amide, to give pentafluoroalcohols. A subsequent oxidation with Dess-Martin periodinane provides the targets in good isolated yields.

  • Conversion of methyl ketones and methyl sulfones into α-deutero-α,α-difluoromethyl ketones and α-deutero-α,α-difluoromethyl sulfones in three synthetic steps

    Deuterodifluoromethyl ketones and sulfones were assembled in three synthetic steps from methyl ketones and sulfones, respectively. The key synthetic transformation is the deuteration of the difluorocarbanion generated by the release of trifluoroacetate from highly α-fluorinated gem-diols. High levels of deuterium on the "CF2D" group were routinely observed. This strategy is mild and versatile and it
