palladium-catalyzed intramolecular hydroaminocarbonylation of 2-(1-methylvinyl)aniline derivatives has been achieved using dppp (1,3-bis(diphenylphosphino)propane) as a ligand under hydrogen-free conditions. The reaction involves the generation of an active palladium hydride species with a catalytic amount of TsOH. This amide bond formation reaction was applied to the synthesis of various 4-substituted 3,4-dihydroquinolone
在无氢条件下,使用 dppp(1,3-双(二苯基膦基)丙烷)作为配体实现了钯催化的 2-(1-甲基乙烯基)苯胺衍生物的分子内加氢氨基羰基化反应。该反应涉及生成具有催化量的 TsOH 的活性氢化钯物质。该酰胺键形成反应用于合成各种 4-取代的 3,4-二氢喹诺酮衍生物,具有高产率和区域选择性。
