A chiral derivative of 1,2-benzenedisulfonimide,(-)-4,5-dimethy1-3,6-bis(o-toly1)-1,2-benzenedisulfonimide is herein proven to be an efficient chiral catalyst in a one pot three-component Mannich protocol. Reaction conditions are mild and green, while the enantio- and diastereoselectivity are excellent. (C) 2015 Elsevier Ltd. All rights reserved.
