activation/cyclization of simple, cheap, and easily available anilines with alkynes for direct and highly efficient synthesis of privileged quinolines with exclusive regioselectivity and broad substrate/functional group tolerance and in good to excellent yields, where DMSO was employed as both the solvent and the C1 building block of quinoline products, is reported. Mechanistic experiments revealed that
独特的Co(III)催化和DMSO参与的C–H活化/环化,具有炔烃的简单,廉价且易于获得的苯胺,可直接高效地合成特权喹啉,具有独特的区域选择性和广泛的底物/官能团耐受性,且在据报道,使用DMSO作为溶剂和喹啉产品的C 1结构单元时,收率良好。机理实验表明,通用反应可能采用2-乙烯基苯甲胺类物质作为活性中间体。
