A palladium-catalyzed annulation of ortho-vinylanilines with dimethylsulfoxide was developed to access 4-aryl quinolines in moderate to good yields. Activated by 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO), DMSO served as a “CH–” fragment in this transformation. It represents a facile pathway leading to 4-aryl quinolines.

An efficient CH3SO3H-promoted synthesis of quinolinesfrom readily available anilines, acetophenones and DMSO under air is reported. This protocol gives diverse substituted 4-arylquinolines in moderate to high yields with broad substrate/functional group tolerance. Preliminary mechanistic studies demonstrate that DMSO may be transformed to HCHO in this process and used as a one carbon source.
据报道,在空气中,CH 3 SO 3 H有效地促进了苯胺,苯乙酮和DMSO的喹啉合成。该方案以中等至高产率提供了多种取代的4-芳基喹啉,具有宽的底物/官能团耐受性。初步的机理研究表明,DMSO在此过程中可能转化为HCHO,并用作一种碳源。
