2'-Hydroxy-5'-methoxyacetophenone Chemical Properties,Usage,Production
Chemical Properties
yellow crystalline powder
Uses
2′-Hydroxy-5′-methoxyacetophenone is observed as a side reaction product of elbs persulphate oxidation of phenols. 2-Hydroxy-5-methoxyacetophenone is also used to prepare substituted chromanone and chromone derivatives as sirtuin 2-selective inhibitors.
Application
2'-Hydroxy-5'-methoxyacetophenone could find some use in perfume compositions, e. g., in artificial Oakmoss, in New Mown Hay fragrances, and in certain heavy florals. It blends well with Labdanum and with Lavender type oils, and it lends a certain amount of power and undertones to the fragrance.
Preparation
reparation by reaction of dimethyl sulfate on 2,5-dihydroxyacetophenone, ? with potassium carbonate in acetone at r.t. (74%) ; ? with aqueous sodium hydroxide solution at reflux (35%).

General Description
2′-Hydroxy-5′-methoxyacetophenone is observed as a side reaction product of elbs persulphate oxidation of phenols.
Synthesis
77-78-1
490-78-8
705-15-7
To a suspension of 2,5-dihydroxyacetophenone (100 mg, 0.66 mmol) and potassium carbonate (95 mg, 0.69 mmol) was added dimethyl sulfate (87 mg, 0.69 mmol) and the reaction mixture was stirred at room temperature overnight. After completion of the reaction, the mixture was filtered and concentrated under reduced pressure. The resulting residue was treated with 2N NaOH aqueous solution and subsequently extracted with EtOAc. The organic layers were combined, washed with saturated saline, dried over anhydrous MgSO4 and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography with hexane-EtOAc (10:1, v/v) as eluent to afford 2'-hydroxy-5'-methoxyacetophenone in 40% yield as a colorless oil.1H NMR (400 MHz, CDCl3) δ: 11.9 (s, 1H), 7.18 (d, J = 2.8 Hz, 1H), 7.12 (dd, J = 8.8, 2.8 Hz, 1H), 6.93 (d, J = 8.8 Hz, 1H), 3.81 (s, 3H), 2.63 (s, 3H).
