    • General procedure for the chiral amine/l-proline co-catalyzed reaction: To a solution of aldehyde (2 mmol), chiral amine and l-proline in 2.5 mL of solvent was added MVK (6 mmol). Then the resulting mixture was stirred at 20 °C for completion of the reaction (monitored by TLC). After removal of solvent, the residue was purified by column chromatography on silica gel (200-300 mesh, gradient eluted with petroleum ether/ethyl acetate) to afford the product.
