  • Reactive dienophiles containing a difluoromethylenephosphonato group
    作者:Kevin Blades、Thierry P. Lequeux、Jonathan M. Percy
    DOI:10.1039/cc9960001457
    日期:——
    New dienophiles containing the difluoromethylenephosphonato group are synthesised from readily-available starting materials and cycloadditions with reactive dienes are executed successfully.

  • Synthesis of activated alkenes bearing the difluoromethylenephosphonate group: a range of building blocks for the synthesis of secondary difluorophosphonates
    作者:Kevin Blades、Afshan H. Butt、G. Stuart Cockerill、Howard J. Easterfield、Thierry P. Lequeux、Jonathan M. Percy
    DOI:10.1039/a907052d

    Active methylene compounds reacted readily with stable hydrate 2-diethoxyphosphoryl-2,2-difluoroethane-1,1-diol to afford a range of activated alkenes bearing the difluoromethylenephosphonate group, a useful motif in the synthesis of phosphate ester mimics of biological interest. Wadsworth–Horner–Emmons reactions were employed using modified Rathke conditions for the syntheses of alkenoates, an alkenoic acid and a vinyl sulfone, while a Henry reaction followed by E1cB dehydration afforded an enedioate and a nitroalkene. A vinyl sulfoxide was less straightforward to synthesise and dephosphorylation to a difluoromethyl congener accompanied attempts to force the reaction to completion.
    活性亚甲基化合物与稳定的水合物2-二乙氧基磷酸酯-2,2-二氟乙烷-1,1-二醇反应,迅速生成一系列带有二氟亚甲基磷酸酯基团的活化烯烃,这是一种在合成生物学兴趣的磷酸酯类似物中有用的结构单元。采用改进的Rathke反应条件进行Wadsworth–Horner–Emmons反应,合成了烯酸酯、一种烯酸和一种乙烯基磺酮,而亨利反应后进行E1cB脱水则得到了一个环烯酸酯和一个硝基烯烃。合成乙烯基亚磺酰氧化物的过程较为复杂,去磷酸化生成二氟亚甲基同系物的尝试伴随着推动反应完成的努力。
  • Facile syntheses of α,α-difluoro-β-ketophosphonates
    作者:Thierry P. Lequeux、Jonathan M. Percy
    DOI:10.1039/c39950002111
    日期:——
    The cerium-mediated reaction between lithio (diethyldifluoromethyl)-phosphonate 2 proceeds smoothly to afford good yields of ketophosphonates; the reaction with DMF led to the formation of the corresponding aldehyde which was isolated as a hydrate with interesting and useful properties.
    铈介导的(二乙基二氟甲基)-膦酸锂 2 反应进行顺利,可得到产率很高的酮膦酸盐;与 DMF 反应可生成相应的醛,并分离出具有有趣和有用性质的水合物。
  • 1,3-Dipolar Cycloaddition of Diazomethane to 1,1-Difluoroallylphosphonates: Application to Synthesis of Cyclopropane Derivatives Having a Diethoxyphosphoryldifluoromethylene Unit
    作者:Tsutomu Yokomatsu、Kenji Suemune、Tetsuo Murano、Shiroshi Shibuya
    DOI:10.3987/com-01-s(k)35
    日期:——
    1,3-Dipolar cycloaddition of diazomethane to (1,1-difluoroallyl)phosphonates was examined to give pyrazolines functionalized by a diethoxyphosphoryldifluoromethylene unit. The pyrazolines were transformed to the cyclopropane derivatives possessing a diethoxyphosphoryldifluoromethylene functionality by photolysis.
