最近看关于钯催化氧化的文献，有几句话需要专业点翻译，请教各位虫友帮助 An efficient Pd(II)-catalyzed difunctionalization reaction of internal alkynes is reported. In this reaction, various enynoates and electron-deficient alkenes were used for the syntheses of useful highly substituted pyrone derivatives via a 6-endo cyclization and subsequent alkenylation pathway. First, a 6-endo cyclization of the enynoate will occur which was activated by the alkyne Pd(II) ion. Therefore, an active vinylpalladium species B will be generated to react with methyl acrylate and afford the intermediate C via migratory insertion. The desired product 3a could be formed after reductive elimination and followed by the reoxidation of Pd(0) species into the next catalytic cycle by benzoquinone (BQ). |
