Abstract

Both enantiomers of trans-2,3-diphenylphosphinomethyl-norbornene-(5), prepared by two independent synthetic routes, were used as ligands in the asymmetric hydrogenation of α-acetamidocinnamic acid in the presence of rhodium(I). Small variations in the ligand structure have a remarkable influence on the activity of the catalytic system.

Abstract

Оба энантиомера транс-2,3-дифенил-фосфинометил-норборнена-(5), синтезированные двумя независимыми путями, были исследованы как лиганды в асимметрическом гидрировании α-ацетамидокоричной кислоты в присутствии родия(I). Небольшое изменение структкры лигандов приводит к заметному изменению активности каталитической системы.
