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
Journal of Organic Chemistry, 2014Co-Authors: Hong Gao, Jing Sun, Chaoguo YanAbstract:The functionalized spiro[indoline-3,2′-pyridine]-3′,4′,5′,6′-tetracarboxylates were efficiently synthesized by BF3·OEt2-catalyzed reactions of isatin-3-imines with Acetylenedicarboxylates in methylene dichloride. Under similar conditions, the BF3·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.
