摘要：

A new type of pyrrolidine-based organocatalyst has been developed and found to be very effective for the domino Michael/Henry reaction in aqueous solvents. For the reaction involving pentane-1,5-dial and various nitroolefins, good yields (6585%) and excellent enantioselectivities (99%) were obtained using this catalyst. In addition, the catalyst could be recycled up to four times resulting in good yields and up to seven times with good enantioselectivity.
