silver-catalyzed decarboxylative radical addition/cyclization reaction of α,α-difluoroarylacetic acids and acrylamides has been disclosed. The method provides a highly attractive approach to synthesize a series of difluorinated oxindoles that contain various functional groups in moderate to good yields under mild conditions. Moreover, experimental studies reveal that the CF2 group of the α,α-difluoroarylacetic
已经公开了一种简便的银催化脱羧自由基加成/环化反应,α,α-二氟芳基乙酸和丙烯酰胺。该方法提供了一种极具吸引力的方法,可以在温和条件下以中等至良好的产率合成一系列含有各种官能团的二氟化羟吲哚。此外,实验研究表明,α,α-二氟芳基乙酸的 CF2 基团在转化中起着至关重要的作用。
