An enantioselective catalytic vicinal diamination of styrenes is reported, which proceeds under entirely intermolecular reaction control. It relies on a chirally modified aryliodine(I) catalyst and proceeds within an iodine(I/III) manifold with conventional 3-chloroperbenzoic acid as a terminal oxidant. An environmentally benign solvent combination not only adds to the attractiveness of the process but also slows down the rate of the undesired background reaction. A total of 30 examples are presented, which consistently provide high enantiomeric excesses in the range 91-98%.

Metal-free and asymmetric: The first enantioselective diamination of styrenes simply requires a chiral hypervalent iodine(III) reagent as an oxidant and bismesylimide as a nitrogen source (see scheme, Ms=methanesulfonyl). The reaction proceeds under mild conditions and with high enantiomeric excess.
