The first palladium-catalyzed ortho-amidation of ketoximes has been developed with readily available, easy to handle and environment-friendly N,N-disubstituted oxamic acids as the amidation sources. When N-monosubstituted oxamic acids are used as the substrates, the formed ortho-amidated ketoximes undergo further intramolecular cyclization to provide 3-methyleneisoindolinones.
发展了首例钯催化的酮肟邻位酰胺化反应,使用易得、易处理且环境友好的 N,N-二取代羟胺酸作为酰胺化试剂。当使用 N-单取代羟胺酸作为底物时,生成的邻位酰胺化酮肟进一步进行分子内环化,得到 3-亚甲基异吲哚啉酮。
