The p-toluenesulfonic acid catalyzed Povarov reaction of isatin-3-imines with beta-enamino esters, which were generated in situ from the reaction of arylamines and methyl propiolate in ethanol, afforded the polysubstituted spiro[indoline-3,2'-quinolines] in high yields and with high diastereoselectivity.
