     “Evaluation of the Chiral DIANANE Backbone as Ligand for Organolithium Reagents”
     Adv. Synth. Catal. 2012, 354, 1780-1790.

Novel endo,endo-2,5-diaminonorbonanederived tertiary C2-symmetrical diamines were synthesized via the one-pot reductive amination of enantiomerically pure norbornane-2,5-dione. These ligands were applied to various catalytic reactions such as asymmetric deprotonation, asymmetric bromine-lithium exchange, and enantioselective addition of aryl- and allkylithium reagents to aromatic aldimines.
