type [CpMo(CO)3X] containing ligands of the formula X = CHR2CO(OR1) where R1 = ethyl (1), menthyl (4), and bornyl (5) and R2 = H; R1 = ethyl and R2 = methyl (2) and phenyl (3) have been synthesized and characterized by NMR and IR spectroscopy and X-ray crystallography. These compounds have been applied as catalystprecursors for achiral and chiralepoxidation of unfunctionalized olefins with tert-butyl

micromolar concentrations both in paraganglioma and pancreaticcancercells. Derivative 4l showed a greater antiproliferative effect and higher selectivity index againstcancercells, as compared to other compounds. Notably, combinations of derivative 4l with gemcitabine at low concentrations induced enhanced and synergistic effects on pancreaticcancercell viability, thus supporting the relevance of compound
