achieved for the first time through cooperative catalysis of proline and brucine N-oxide. A unique mode of activation of the aldehydes through proline iminium intermediates has been identified as a key reaction parameter for the successful MBH reaction of aryl vinyl ketones. The reaction pathways leading to 1:2 MBH products under typical nucleophiliccatalysis conditions were investigated. A systematic
