  Selective Synthesis of Functionalized Spiro[indoline-3,2′-pyridines] and Spiro[indoline-3,4′-pyridines] by Lewis Acid Catalyzed Reactions of Acetylenedicarboxylate, Arylamines, and Isatins

  摘要：

  The functionalized spiro[indoline-3,2'-pyridine]-3',4',5',6'-tetracarboxylates were efficiently synthesized by BF3 center dot OEt2-catalyzed reactions of isatin-3-imines with acetylenedicarboxylates in methylene dichloride. Under similar conditions, the BF3 center dot OEt2-catalyzed three-component reactions of acetylenedicarboxylates, arylamines, and isatins afforded functionalized spiro[indoline-3,4'-pyridine]-2',3',5',6'-tetracarboxylates in moderate yields.

  日期：——

  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.
