  • Phosphine-Catalysed Cyclisation of β-Hydroxy-α,α-Difluoroynones
    作者:Véronique Gouverneur、Marie Schuler、Angèle Monney
    DOI:10.1055/s-0029-1217366
    日期:2009.7
    2-Benzylidene-4,4-difluorodihydrofuran-3(2H)-ones were synthesised in 58―86% yield via phosphine-promoted cyclisation of β-hydroxy-α,α-difluoroynones. The benzylidene group was found to be a suitable masked carbonyl group, thereby allowing for the validation of a novel route to 3,3-difluoro-2-hydroxy-γ-lactols.
    2-亚苄基-4,4-二氟二氢呋喃-3(2H)-酮通过膦促进的β-羟基-α,α-二氟炔酮环化反应以58-86%的产率合成。亚苄基被发现是一个合适的掩蔽羰基,从而允许验证一种新的途径来获得 3,3-二氟-2-羟基-γ-内酯。
  • An Efficient and General Method for the Reformatsky-Type Reaction of Chlorodifluoromethyl Ketones with Carbonyl Compounds Giving α,α-Difluoro-β-hydroxy Ketones
    作者:Manabu Kuroboshi、Takashi Ishihara
    DOI:10.1246/bcsj.63.428
    日期:1990.2
    Specific activation of zinc metal with the metal salt is essential to achieve high efficiency of the reaction, depending upon the structures of the chlorodifluoromethyl ketones and the carbonyl compounds employed. In-situ formed intermediates in these reactions were successfully detected by 19F NMR spectroscopy, which suggests that their structure is not an α-metallo ketone but an oxygen-metallated
    氯二氟甲基酮 CF2ClCOR,其中 R 是烷基、芳基和 1-炔基,在酸洗锌粉和氯化铜 (I) 或银存在下,与多种醛或酮发生 Reformatsky 型羟醛反应醋酸盐得到相应的 α,α-二氟-β-羟基酮,收率很好。根据氯二氟甲基酮和所用羰基化合物的结构,用金属盐对锌金属进行特定活化对于实现反应的高效率是必不可少的。这些反应中原位形成的中间体通过 19F NMR 光谱成功检测到,这表明它们的结构不是 α-金属酮,而是具有锌 (II) 金属作为抗衡阳离子的氧金属化物质。
  • Synthesis and Application of <i>β</i> ‐Alkynyl‐ <i>γ</i> , <i>γ</i> ‐Difluoroallylboronates for Metal‐Free Allylation of Aldehydes in Water
    作者:Jian‐Lin Xu、Chao Yang、Dong‐Ting Dai、Wei‐Shu Hou、Yun‐He Xu

    日期:2022.3.30
    β-Alkynyl substituted γ,γ-difluoroallyl-boronates were prepared via defluorination under basic condition. Allylation reaction of aldehydes with gem-difluoroallylboronates under metal-free condition in water was developed. As the sole solvent, water dramatically improved the efficiency of the reaction, and afforded the desired products in 48–92% yields. The corresponding difluorinated alcohols were

    Salicylidene acylhydrazides are inhibitors of type III secretion in several Gram-negative pathogens. To further develop the salicylidene acylhydrazides, scaffold hopping was applied to replace the core fragment of the compounds. The novel 2-(2-amino-pyrimidine)-2,2-difluoroethanol scaffold was identified as a possible analog to the salicylidene acylhydrazide core structure. The synthesis of a library of 2-(2-amino-pyrimidine)-2,2-difluoro-ethanols is described in this paper.
