  The first Pd(II)-catalyzed C–H addition to isatins by direct sp2/sp3 C–H bond activation for the construction of 3-substituted-3-hydroxy-2-oxindoles is reported. The bidentate nitrogen ligands were found to promote this reaction. Specifically, the preliminary bioassay indicated that 3-(5-chlorobenzoxazole)-3-hydroxy-N-benzyl-2-oxindole (2w) is a new inhibitor of human kidney cancer and hepatocellular

  据报道，通过直接的sp 2 / sp 3 C-H键活化，Pd（II）催化的CHs可以直接形成3-取代的3-羟基-2-羟基吲哚，并通过直接的sp 2 / sp 3的CH键活化。发现双齿氮配体促进该反应。具体地，初步的生物测定表明3-（5-氯苯并恶唑）-3-羟基-N-苄基-2-氧吲哚（2w）是人肾癌和肝细胞癌细胞的新抑制剂。而且，该反应体系表现出很大的官能团耐受性，并且不需要导向基团，额外的碱或添加剂。
