A novel one-pot three-component asymmetric Mannich reaction using [EMIm][Pro] (1) as a catalyst has been developed. By employing this new reaction system, a variety of optically active beta-amino carbonyl compounds were synthesized in up to 99% yield with up to > 99 dr and > 99% ee The reaction conditions have been optimized and the mechanism for the asymmetric induction IS discussed
