exhibits the highest catalytic performance working in an aqueous medium. It catalyzed the directcatalyticasymmetric intermolecular aldolreaction between unmodifiedketones and an aldehyde with excellent stereocontrol and furnished the corresponding aldol products in up to 99% ee. Compound 3a also showed excellent asymmetriccatalytic activity in the asymmetric Michael reaction (up to 99% ee).
