已经开发了α,α-二氟-β-酮酸和无催化剂和无基碱基条件下未受保护的伊萨蛋白的脱羧醛醇反应。这种方法在简单条件下使用低成本可用的原材料在操作上方便,因此可以作为合成3-二氟烷基-3-羟基-2-氧气衍生物的有吸引力的策略,具有中等至优异产率的潜在生物学活性。
The decarboxylative 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 moderate to excellent yields.
