摘要：

A series of chiral ionic phosphite-type ligands bearing pyridinium and imidazolium fragments were prepared. Testing of these ligands in Rh-catalyzed asymmetric hydrogenation of dimethyl itaconate and methyl 2-acetamidoacrylate resulted in 95% ee of the products with 100% conversion of the reactants.
