Abstract
New chiral rhodium complexes of a set of dimenthylphosphine-substituted, crosslinked styrene-divinylbenzene copolymers have been tested for the enantioselective hydrogenation of Z-α-acetamidocinnamic acid. The supported catalysts have been found to give optical yields up to 60% but suffer with respect to the catalytic activity.
Abstract
Были получены новые хиральные комплексы родия на основе диментильфосфина, фиксированного на поверхности сополимера стирола с дивинилбензолом. Комплексы были исследованы в энантиоселективном гидрировании (Z)-α-ацетамидокоричной кислоты. При этом был получен N-ацетил-(R)-фенилаланин с оптическим выходом до 60%.
