Highly diastereo- and enantioselective cross-aldol reactions of aldehydes (> 20 : 1 dr, 99% ee), catalyzed by chiral diamine-polyoxometalate acid combined enamine catalysts in emulsion media, are reported. This type of catalysts can be recycled several times without significant deterioration of activity and selectivity.
