Hydrogenation of (Ej- and (Z)-Methyl-p-methylcinnamate with Rhodium (IIIj-Borohydride Complexes of Chiral Amides... 

Variation of reactant structure was investigated in order to probe the interaction between NADPME and cinchonine (Figure 4). In a series of cinchonine-modified hydrogenations conducted under standard conditions, Z-a-methylcinnamic acid methyl ester (II) gave... 

Beamer et al. used Pd-polymer catalysts in the hydrogenation of the C=C bonds in 2-acetamidocinnamic acid to iV-acetylphenylalanine (Scheme 3.5.) and 2-methylcinnamic acid to 2-methyl-3-phenylpropanoic acid (Scheme 3.8.). The results are in Table 3.2. 

Smith et al reported that the hydrogenation of 2-methylcinnamic acid and 2-methylpent-2-enoic acid on 1 % Pd-sihca catalysts modified with l-(iS)-e c/o-bomyloxytrimethylsilane in MeOH at 25°C results in chiral products with ee s of 22.5% and 11.6%. These results noted that modified Pt and Pd catalysts can hydrogenate enantioselectively systems with 1,3-conjugated bonds, but the transfer of these aspects for hydrogenation of 1,4-double bonds as in methyl acetoacetate (MAA) has definite difficulties because it needs to assume the enol form (En) to react (Scheme 5.32.).
