The proline catalyzed two-component and three-component asymmetric Mannich reaction with hydroxyacetone and self-Mannich reaction with propanal were performed successfully under ultrasonic conditions in 1 h to afford Mannich products in 90-98% isolated yi

Efficient chiral catalysts for direct asymmetric three-component Mannich reactions of ketones, aldehydes and an amine (p-anisidine) have been developed. The corresponding β-amino carbonyl compounds (Mannich adducts) were obtained in good chemical yields a

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 ss-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.
