A series of cinchona alkaloid silyl ether derivatives have been used to catalyze the enantioselective Friedel-Crafts reaction of indoles with isatins. The resulting 3-hydroxy-2-oxindoles were obtained in good yields (78%~96%) with high enantioselectivities (up to 99% ee). The catalyst type and the substrate scope were broadened in this methodology.

Key words: cinchona alkaloid silyl ether, organocatalysis, isatin, indole, enantioselective Friedel-Crafts reaction
