Readily available, recoverable and soluble polymer-monophosphite ligands for highly enantioselective Rh-catalyzed hydrogenation.
A new family of readily available, recoverable and soluble polymer-monophosphite ligands were prepared and successfully used in the Rh-catalyzed asymmetric hydrogenation of enamides and beta-dehydroamino acid esters, in which up to 99 and 99.9% ee were obtained, respectively.
