实验步骤: In a 40 mL vial, 4-Pentyl-cyclohexanol (1144.4 mg, 0.0067202 mol) was diluted with tetrahydrofuran (30.0 mL, 0.370 mol, Acros) and subsequently (R)-4-(6-hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (1.4924 g, 0.0061350 mol) and triphenylphosphine (2105.5 mg, 0.0080275 mol) were added and the mixture was stirred. Diethyl Azodicarboxylate in toluene (2.6 mL, 0.0086326 mol, Aldrich) was added, and the mixture was then stirred at room temperature for 38 h. The reaction mixture was evaporated to dryness and chromatographed 0-100% EtOAc/Hexanes (adsorbed onto silica gel). Isolated was 0.6142 g (18%) in approx 70% purity, the remainder being reduced DEAD reagent. were added the mixture was then stirred at room temperature for 38 h The reaction mixture was evaporated to dryness chromatographed 0-100% EtOAc/Hexanes (adsorbed onto silica gel) Isolated

实验步骤: (R)-4-(6-Hydroxnaphthalen-2-yl)-4-methyl-oxazolidin-2-one (Example 4, 0.3303 g, 0.001358 mol) was added to a capped 40 mL vial equipped with a magnetic stir bar. 4-Pentyl-cyclohexanol (0.277 g, 0.00163 mol) was added, followed by tetrahydrofuran (6.00 mL, 0.0740 mol). Triphenylphosphine polymer-bound (1.17 g, 0.00217 mol) was then added and the mixture was stirred for 5 minutes. Diisopropyl azodicarboxylate (0.428 mL, 0.00217 mol) was then added and the mixture was stirred for 48 hours at room temperature. The mixture was diluted in ethyl acetate, filtered through CELITE™, concentrated under vacuum and purified by flash chromatography (0-5% MeOH in dichloromethane) to give 0.3672 g of the title compound (68% yield). vial equipped with a magnetic stir bar the mixture was stirred for 48 hours at room temperature filtered through CELITE™ concentrated under vacuum purified by flash chromatography (0-5% MeOH in dichloromethane)

实验步骤: Under argon, to a solution of 4-pentylcyclohexanol (2.0 g, 11.75 mmol) in anhydrous THF (60 mL), NaH was added (60%, 0.94 g, 23.5 mmol) at 0° C. and stirred for 30 minutes, followed by the addition of dimethyl sulfate (1.68 mL, 17.62 mmol). The mixture was refluxed for 12 hrs and cooled to 0° C. The reaction was quenched with saturated ammonium chloride solution (20 mL). THF was removed under vacuum and the residue was extracted with CH2Cl2 (3×25 mL). The collected organic portion was dried with Na2SO4 and concentrated. The crude product was purified by flash chromatography (hexanes/ethyl acetate: 15/1) to provide probe 1 (2.0 g, quant.) as a colorless liquid. 1H NMR (400 MHz, CDCl3): δ=0.79-0.85 (m, 10 H), 1.28-1.38 (m, 7 H), 1.46 (br, 2 H), 2.02 (br, 2 H), 3.32 (s, 3 H). 13C NMR (100 MHz, CDCl3): δ=8.1, 20.9 (2 carbons), 24.1 (2 carbons), 30.2 (2 carbons), 32.6, 34.8, 45.2, 55.5, 74.8; MS (ESI) calcd for C12H25O [M+H]+/z: 185.19. found: 185.31.
