ENANTIOSELEKTIVE KATALYSE, 63 - OPTISCH AKTIVE PHOSPHINE AUS DICARBONSAEUREN UND IHR EINSATZ IN DER ENANTIOSELEKTIVEN HYDRIERUNG

Two optically active bident phosphine ligands were synthesized from derivatives of succinic acid as starting materials.The optical resolution of the acids was carried out with cinchonidine and (S)-α-phenylethylamine.In the Rh-catalyzed enantioselective hydrogenation of α-acetamidocinnamic acid, the bisphosphine with a phenyl substituent in the 2-position of the four-carbon chain gave enantiomeric excess of 17percent.The enantiomeric excess was twice as high with the corresponding thienyl substituted biphosphine.
