readily available organomagnesium reagents were used for the catalytic enantioselectivealkylation of enolizable N‐sulfonyl ketimines. The low reactivity and competing enolization of the ketimines was overcome by the use of a copper–phosphine chiral catalyst, which also rendered the transformation highly chemoselective and enantioselective for a broad range of ketimine substrates.
