isoindolinones via the direct coupling of N -methoxybenzamides and bis(tosylamido)methane with rhodium(III) as catalyst has been developed. The reaction is performed under mild conditions, without oxidant, and is compatible with various functional groups. Compared with the previously reported method for constructing isoindolinone skeletons, this method involves a novel [3+2] cyclization, and affords a wide
开发了一种通过 N-甲氧基苯甲酰胺和双(甲苯磺酰氨基)甲烷与铑 (III) 作为催化剂直接偶联来合成异吲哚啉酮的新方法。该反应在温和条件下进行,无氧化剂,与多种官能团相容。与先前报道的构建异吲哚啉酮骨架的方法相比,该方法涉及一种新的 [3+2] 环化,并以中等至优异的产率提供了多种异吲哚啉酮。
