Supporting and recycling of chiral catalysts are still the most important scientific issues.Nano-size dendrimers serve as a promising type of catalyst support due to their well-defined and tunable three-dimension molecular architectures as well as their unique physical and chemical properties.Cinchona alkaloid catalysts are widely used in asymmetric catalytic reactions such as asymmetric dihydroxylation reaction, Mannich reaction, Diels-Alder reaction. Dendritic cinchona alkaloid catalysts were obtained from different generations of dendritic benzyl alcohols, 1,4-dichlorophthalazine and dihydr...
