  Au-catalyzed intramolecular hydroalkoxylation of gem-difluorinated alkynols

  摘要：

  The intramolecular hydroalkoxylation of gem-difluorinated alkynols was found possible under Au catalysis, allowing for the preparation of a series of fluorinated heterocycles. The nature of the solvent was found to be especially critical in the cyclization of gem-difluorohomopropargylic alcohols as it dictated whether the resulting 2,3-dihydrofuran underwent subsequent aromatization to the corresponding furan or not.

• A novel approach of cycloaddition of difluorocarbene to α,β-unsaturated aldehydes and ketones: synthesis of gem-difluorocyclopropyl ketones and 2-fluorofurans

  acetals and ketals are easily obtained in moderate yields from the [1 + 2] cycloaddition of difluorocarbene to 1,3-dioxolanes of alpha,beta-unsaturated aromatic aldehydes and ketones. Hydrolysis of these fluorinated compounds under acidic conditions either gives the corresponding gem-difluorocyclopropyl ketones or 1-aryl-2-fluorofuran derivatives through intramolecular carbonium rearrangement with simultaneous

  从二氟卡宾的[1 + 2]环加成到α，β-不饱和芳族醛和酮的1,3-二氧戊环上，可以容易地以中等收率获得一系列的宝石-二氟环丙基缩醛和缩酮。这些氟化化合物在酸性条件下的水解可通过分子内碳原子重排并同时裂解环而得到相应的宝石二氟环丙基酮或1-芳基-2-氟呋喃衍生物。
• Selective Synthesis of Fluorinated Furan Derivatives via AgNO₃-Catalyzed Activation of an Electronically Deficient Triple Bond

  The transition metal-catalyzed direct activation of electron deficient triple bonds was investigated by using the combined electron withdrawing effects of two fluorine atoms to modulate the electronic density of the triple bond. With use of catalytic amounts of AgNO3 (10 mol %) the synthesis of substituted 3,3-difluoro-4,5-dihydrofurans from gem-diflou rohomopropargyl alcohols occurred in excellent NMR yields. Treatment of these dihydrofurans with SiO2 or Pd/H-2 yielded the corresponding 3-fluorinated furans and 3,3-difluorotetrahydrofurans.
