Aqueous-phase hydrogenation of biomass-derived itaconic acid to methyl-γ-butyrolactone over Pd/C catalysts: Effect of pretreatments of active carbon
The effect of active carbon pretreatment on the catalytic performance of Pd/C catalysts in the hydrogenation of itaconic acid was studied. The catalysts were prepared by deposition-precipitation and characterized by XRD, BET, NH3-TPD, TEM and F

Highly regioselective intramolecular hydroxymethylation of α,β-unsaturated carboxylic acids
A convenient synthesis of hydroxy esters 7 and lactones 8 by starting from easily available α,β-unsaturated carbocylic acids 4 is described. The key step of this transformation is a hitherto unknown radical cyclization of silyl esters, which exhibits a high degree of regioselectivity through steric and orbital control.

Asymmetric Hydrogenation of Unsaturated Carboxylic Acids Catalyzed by BINAP-Ruthenium(II) Complexes
Homogeneous hydrogenation of α,β- or β,γ-unsaturated carboxylic acids in the presence of a catalytic amount of Ru(OCOCH3)2 affords the corresponding saturated products in high enantiomeric excesses and in quantitative yields.The new hydrogenation has been applied to the asymmetric synthesis of (S)-naproxen, a 1β-methylcarbapenem precursor, and some methylated γ- and δ-lactones
