Proline-Catalyzed Asymmetric Addition Reaction of 9-Tosyl-3,4-dihydro- β-carboline with Ketones

(Equation presented) 9-Tosyl-3,4-dihydro-β-carboline (1) reacted with a ketone in the presence of (S)-proline as a catalyst to give the corresponding addition product in good yield and high enantioselectivity. In the process, a small amount of water was f
