| 英文摘要 | A series of novel chiral diphosphite ligands was easily prepared in a few steps from commercial (1R,2R)-trans-1,2-cyclohexanediol as the chiral source, and successfully employed in the Rh-catalyzed asymmetric hydrogenation of alpha,beta-unsaturated carboxylic acid derivatives and enamides with up to 99% ee for dimethyl itaconate and enamides and with up to 94% ee for alpha-dehydroamino acid esters. The stereochemically matched combination of (1R,2R)-trans-1,2-cyclohexanediol backbone and (S)-binaphthyl in the ligand (1R,2R)-bis[(S)-1,1'-binaphthyl-2,2'-diyllphosphitecyclohexanediol, was essential for inducing high enantioselectivity. Moreover, the sense of enantiodiscrimination of the products was mainly determined by the configuration of the binaphthyl moieties. |
