A rhodium-catalyzed direct C–H sulfonamidation and amidation of C-7 position of indolines by simple and commercially available arylsulfonamides and trifluoroacetamide has been developed, affording a series of N-arylsulfonamides and N-aryltrifluoroacetamides in moderate to excellent yields, respectively. Notably, this catalytic system is highly convenient on mmol scale.
已开发出铑可通过简单的市售芳基磺酰胺和三氟乙酰胺直接催化C–H磺酰胺化和吲哚的C-7位酰胺化,从而分别以中等至优异的收率提供了一系列N-芳基磺酰胺和N-芳基三氟乙酰胺。值得注意的是,该催化体系在毫摩尔规模上非常方便。
