With manganese(II) oxide; In dichloromethane; at 20℃; for 16h; | Mn02 (35 equiv, 2.2 g) was added to the alcohol (1 equiv, 100 mg) in DCM (20 mL) and the reaction was stirred at room temperature for 16 h. The reaction mixture was filtered and concentrated in vacuo. The residue was used in the next step without further purification |

In acetone; | EXAMPLE 10C Tetrahydrothiophene-3-one-1,1-dioxide A mechanically stirred solution of the crude product from Example 10B in acetone (300 mL) was treated with Jones reagent (2.7M, 30 mL total) in portions over 2 hours until the brown color persisted, stirred for 1 hour, treated slowly with isopropyl alcohol (7.5 mL), stirred for 15 minutes, diluted with acetone (400 mL) and filtered through celite to remove the chromium salts. The filtrate was concentrated and purified by chromatography on silica gel (1:1 hexane:ethyl acetate) to provide 5.88 g of the title compound. 1H NMR (CDCl3) δ 3.08 (t, 2H), 3.58 (t, 2H), 3.70 (s, 2H). |
