An enantio- and regioselective allylic alkylation of sulfoximines with Morita-Baylis-Hillman carbonates was developed. The asymmetric reaction is directed by a quinidine-derived organocatalyst providing a range of optically active α-methylene β-sulfoximidoyl esters in high yields (up to 93%) with good to excellent enantiomeric excesses (up to 95%) under mild reaction conditions.
