英文摘要: A practical, efficient, and environmentally benign intramolecular hydroamination of 2-Phenylethynyl-N-arylsulfonylanilines was developed using commercially available perfluorous super-acid (C8F17SO3H) as a catalyst and alpha,alpha,alpha,-trifluorotoluene as a solvent to produce the corresponding indoles in good yields. The 3-alkylindoles were readily obtained through tandem cyclization/deprotection/Frieciel-Crafts alkylation's reaction in the present of higher catalyst loading of C8F17SO3H. Moreover, N-protected 2, 3-dihydro-1H-quinolin-4-one and 2-acylanilines were also got through the Meyer-Schuster rearrangement and hydration of alkynes under the similar reaction conditions, respectively. The catalyst (C8F17SO3H) could be recyclable and reusable at least three times.
