The α,α-difluoro-β-hydroxyketone skeleton is an important pharmacodynamic structure in the synthesis study of pharmaceuticals. Herein, we describe a novel iron mediated Reformatsky reaction of iododifluoroacetophenones with aldehydes, which offers a relatively more economical and environment friendly route for the construction of α,α-difluoro-β‑hydroxyl ketone with good yield. In addition, iron shows
α,α-二氟-β-羟基酮骨架是药物合成研究中重要的药效结构。在此,我们描述了一种新型的铁介导的碘二氟苯乙酮与醛的Reformatsky反应,该反应为构建具有良好产率的α,α-二氟-β-羟基酮提供了一种相对更经济、更环保的路线。此外,与其他金属相比,铁显示出更广泛的适用性。它可以介导碘二氟苯与α,β-不饱和酮或磺酰亚胺反应,分别得到1,2-加成产物和α,α-二氟-β-氨基化合物。
