摘要：

Plural ligands consisting of catalysts such as AlLibis(binaphthoxide) complex (ALB) and GaNabis(binaphthoxide) complex (GaSB) are effectively introduced onto the periphery of a dendrimer. The resulting dendrimer-supported heterobimetallic catalysts promoted the asymmetric Michael reaction of 2-cyclohexenone with dibenzyl malonate to give the adduct with up to 97% ee.
