4-Benzoyldihydro-3H-furan-2-one → Dihydro-4-(phenylmethyl)-2(3H)-furanone

참여 물질

반응 단계

To a solution of 4-benzoyl-dihydro-furan-2-one (5 g) in methanol (250 mL) in a Parr® reactor is added palladium chloride (0.25 g). The mixture is shaken under hydrogen (50 PSI) for 3 h. The mixture is filtered through a pad of Celite® (40 g) and the filtrate concentrated. The residue is chromatographed on SiO2 (10% ethyl acetate/hexanes, then 30% ethyl acetate/hexanes) to yield the title compound, (2.5 g, 34% from 3-benzoylpropionic acid), as a colorless liquid.
