- W2034711987 abstract "Sechs Zimtsäure- und Acrylsäure-Derivate, die sich nur in einem Substituenten unterscheiden, werden enantioselektiv zu den entsprechenden Phenylalanin- und Alanin-Derivaten hydriert. Als Katalysatoren dienen Mischungen aus [(1,5-COD)RhCl]2 und den optisch aktiven Phosphanen (−)-Norphos, (+)-Prophos, (+)-Diop und (−)-BPPFA. Die Auswertung der Ergebnisse mit der Ruch/Ugi-Theorie zeigt, daß man auch bei Kenntnis der λ-Parameter der Substratsubstituenten und der p-Parameter der Katalysatoren die gefundenen Enantioselektivitäten nicht berechnen kann. Asymmetric Catalyses, 11. Calculation of Enantioselectivities in the Rh-catalyzed Hydrogenation of Amino Acid Precursors with the Ruch/Ugi Model Six cinnamic acid and acrylic acid derivatives, differing only in one substituent, were enantioselectively hydrogenated to give the corresponding phenylalanine and alanine derivatives. As catalysts mixtures of [(1,5-COD)RhCl]2 with the optically active phosphanes (−)-Norphos, (+)-Prophos, (+)-Diop, and (−)-BPPFA were used. The analysis of the results with the Ruch/Ugi theory shows that, even knowing the λ-parameters of the substrate substituents and the p-parameters of the catalysts, the enantioselectivities found cannot be calculated." @default.
