A novel recyclable threonine-derived ionic-liquid-supported organocatalyst of asymmetric cross-aldol reactions has been developed. In its presence, aromatic aldehydes react with hydroxyacetone, methoxyacetone and 2-butanone to afford the corresponding syn-aldol products in moderate to high yields with excellent diastereo- (syn/anti up to 96:4) and enantio-selectivity (up to 95 % ee), which was retained over five recycling experiments.
