An asymmetric aza-Friedel-Crafts alkylation reaction between indoles and indolenines that were derived insitu from 3-indolinone-2-carboxylates has been developed by using 3,3-bis(triphenylsilyl)-1,1-binaphthyl-2,2-diyl hydrogen phosphate as a catalyst. The reaction proceeded under mild conditions and provided chiral indol-3-yl-3-indolinone-2-carboxylate derivatives in good yields with excellent ee values (up to 98.6%). Similarly, the Mannich-type addition of indoline-3-ones to indolenines provided heterodimers with vicinal chiral quaternary centers. This method was successfully applied to the construction of the core structure of trigonoliimineC.
