Enantioselective hydrogenation of the aromatic ring of furancarboxylic acids is an important new application of cinchona-modified palladium as there is no synthetically useful method yet available for this transformation. Here we report a mechanistic investigation of the hydrogenation of furan-2-carboxylic acid. The 5 wt.% Pd/Al2O3 catalyst was chirally modified by cinchonidine (CD) derivatives, (R)-1-(1-naphthyl)ethylamine derivatives, and (R)-1-(1-naphthyl)-ethanol. Variation of the structure of the modifiers revealed that the major requirement an efficient chiral modifier has to fulfill is the presence of a basic N and an OH function. The relative position of the two functional groups and the acidity (proton donor ability) of the OH group are not critical as indicated by the similar efficiency of 1,2- and 1,3-amino alcohols and amino phenols. The enantioselection is attributed to the formation of a cyclic, 2:1 acid:modifier complex that adsorbs close to parallel to the Pd surface via pi-bonding of the aromatic rings of substrate and modifier. The model can interpret also the effect of a strong acid additive. The poor performance of amine type modifiers is attributed to the formation of too flexible, acyclic structures.

In a Article，once mentioned of 43207-78-9

A series of isoquinolines, N-methyl-1,2-dihydroisoquinolines, N-methyl-1,2,3,4-tetrahydroisoquinolines, 1,2,3,4-tetrahydroisoquinolines, and N-methylisoquinolinium ions were tested as inhibitors of monoamine oxidases A and B. All compounds were found to act as reversible and time-independent MAO inhibitors, often with a distinct selectivity towards MAO-A. As a class, the N-methylisoquinolinium ions were found to be the most active MAO-A inhibitors, with N-methyl-6-methoxyisoquinolinium ion emerging as a potent (IC50 = 0.81 muM) and competitive MAO-A inhibitor. Comparative molecular field analysis (CoMFA, a 3D-QSAR method) of MAO-A inhibition was performed using the data reported here and in the literature. Using the steric and lipophilic fields of the inhibitors, quantitative models with reasonable predictive power were obtained that point to the importance of steric, lipophilic, and polar interactions in modulating MAO-A inhibitory activity.
