| Outline of Final Research Achievements |
Cellulose-supported chiral Rh nanoparticle (NP) catalysts have been developed. The Rh NPs, which were well dispersed on cellulose, catalyzed the asymmetric 1,4-addition of arylboronic acids to enones and enoates, one of representative asymmetric carbon-carbon bond-forming reactions, in the presence of chiral diene ligands, providing the corresponding adducts in high yields with outstanding enantioselectivities without metal leaching. The solid state NMR analysis of chiral NP system directly suggested interactions between the Rh NPs and the chiral ligand on the cellulose. This is the first example of polysaccharide-supported chiral metal nanoparticles for asymmetric carbon-carbon bond-forming reactions.
