Abstract

Enantioselective construction of pyrroloindolines via chiral phosphoric acid catalyzed cascade Michael addition-cyclization of tryptamines has been realized. With 5 mol % of chiral phosphoric acid, enantioenriched pyrroloindoline derivatives were obtained in good yields and enantioselectivity (up to 95% yield and 83% ee) from readily available tryptamines and enones.
