Abstract
The first example of catalytic enantioselective aza-Henry reaction of ketoimines has been realized using a simple chiral N,N'-dioxide-Cu(I) complex as catalyst. It performs well over a range of substrates to give the corresponding products in moderate to good yields (up to 83%) with high enantioselectivities (up to 96% ee).
