Enantioselective C-C bond formation to 2-pyridinesulfonylimines afforded products with good enantioselectivity. Dynamic induction of chirality on the sulfur by coordination of a chiral Lewis acid to the pyridine nitrogen and one of the prochiral sulfonyl oxygens induces enantioselectivity. Since the 2-pyridine-sulfonyl group can easily be removed after the reaction, it acts not only as an activating group but also as an efficient Stereocontroller.
