실험 절차

A solution of (3S),(7R) 4-carbomethoxy-3-(3-nitrophenyl)-7-(2-phenylethyl)-7-[(4-phenylphenoxy)methoxy]decan-5-ol (XIV, EXAMPLE 10, 11.12 g, 79.0 wt %, 13.73 mmol) in methylene chloride (530 ml) is added to a ground mixture of pyridinium chlorochromate (16.099 g, 74.685 mmol, 5.44 eq), sodium acetate (6.984 g, 85.14 mmol, 6.20 eq) and florisil (5.181 g) while maintaining less than 11°. The mixture is warmed to 21° and stirred at 20-25° for 20 hrs. The resultant slurry is filtered through magnesol (47.7 g) and rinsed with methylene chloride (375 ml). The filtrate is concentrated to an oil. An analytical sample of the title compound is obtained by chromatography (ethyl acetate/hexanes): TLC Rf =0.34 (ethyl acetate/hexanes, 10/90); HPLC rt=13.02, 13.23 min; NMR (CDCl3) 8.05-8.01, 7.60-7.00, 5.37, 5.21, 4.03, 3.94, 3.75, 3.58-3.43, 3.39, 2.96, 2.78-1.37, 1.20, 0.91, 0.71-0.61 δ; CMR (CDCl3) 200.89, 200.60, 168.29, 167.81, 157.10, 157.05, 148.38, 148.30, 143.58, 143.32, 141.99, 141.93, 140.73, 140.69, 135.29, 135.01, 134.78, 129.38, 129.23, 128.75, 128.45, 128.36, 128.23, 126.77, 125.91, 125.80, 122.96, 122.80, 122.04, 122.00, 116.16, 87.14, 86.92, 80.93, 80.44, 66.34, 65.92, 52.79, 52.35, 49.02, 48.62, 46.28, 46.20, 38.70, 38.51, 38.43, 37.99, 30.10, 29.52, 26.92, 26.71, 16.64, 16.39, 14.39, 14.16, 11.81, 11.58; MS (CI, ammonia) m/z (relative intensity) 656 (2.8), 655 (6.1), 136 (100).
