実験手順
Methyl 3,5-dioxohexanoate (19.0 g) was dissolved in THF (380 mL) and tris(triphenylphosphine) ruthenium (II) dichloride (1.1 g) was added. The reaction mixture was hydrogenated at 5 bar, 50° C. for 16 h and then cooled to room temperature. The solvent was removed under vacuum and the oil was purified on silica gel (hexane/EtOAC 1:1) to give the final methyl 3-hydroxy-5-oxohexanoate (10 g).
