An efficient enantioselective Michael addition of 2-naphthols to alkylideneindolenines generated in situ from arenesulfonylalkylindoles has been described. The protocol provides an efficient and convenient access to C-3 alkyl-substituted indole derivatives containing phenolic hydroxyl groups with high yields (up to 96%) and enantioselectivities (up to 98% ee) under mild conditions.
