aldol reaction of α,α-difluoro-β-keto acids and unprotected isatins under catalyst- and base-free conditions has been developed. This method is operationally convenient under simple conditions using low-cost readily available raw materials, and therefore could serve as an attractive strategy for the synthesis of 3-difluoroalkyl-3‑hydroxy-2-oxindole derivatives with potential biological activities in
α,α-二氟-β-酮酸和未保护的靛红在无催化剂和无碱条件下的脱羧醛醇反应已得到开发。该方法在简单条件下操作方便,使用低成本易得的原材料,因此可以作为一种有吸引力的策略来合成具有潜在生物活性的 3-二氟烷基-3-羟基-2-羟吲哚衍生物,收率中等至极好.
