实验步骤: 2-Ethylcyclohexanol (1.6 moles, 204 g, 226 mL) was stirred in 3.2 l of acetone at 0° C. and treated with 8N Jones reagent (prepared from 106.8 g of CrO3 suspended in 92 mL of concentrated sulfuric acid and diluted to 400 mL with water) until the orange color persisted (~430 mL). Isopropanol was then added to turn the solution green again after which it was poured into 2 l of ether. The product was washed with 6×500 ml of brine, dried over MgSO4 and stripped of solvent. Short path distillation (b.p. 80°-85° C. at 25 mm) afforded 184 g (1.46 moles, 91%) of 2-ethylcyclohexanone as a colorless oil. The product was washed with 6×500 ml of brine dried over MgSO4 Short path distillation (b.p. 80°-85° C. at 25 mm)

实验步骤: Celite (25 g) and pyridinium chlorochromate (PCC, 25 g, 1.5 eq, 0.12 moles) were added consecutively to a solution of commercially available 2-ethylcyclohexanol (10 g, 78 mmol) in 300 mL CH2Cl2. The resulting reaction mixture was stirred at room temperature for 1 hour after which it was filtered and concentrated on the rotary evaporator. The residue was purified by column chromatography using EtOAc/hex (1:2) as eluant to give 7.57 g (77%) of the title ketone. Spectroscopic data: 1H NMR (CDCl3, 300 MHz) δ=0.89 (t, 3H, J=7.47 Hz), 1.18-1.45 (m, 2H), 1.63-1.89 (m, 4H), 1.99-2.42 (m, 5H). The resulting reaction mixture was filtered concentrated on the rotary evaporator The residue was purified by column chromatography
