실험 절차

To a solution of 2-phenyl-1-(2-phenyl-[1,3]-dithian-2-yl)-ethanol (66) (2.50 g, 7.9 mmol) in 100 mL of a 9:1 mixture of acetonitrile and water was added mercuric perchlorate hydrate (4.1 g, 10.3 mmol). The resulting mixture was stirred at room temperature for 5 minutes and thin layer chromatography indicated that the reaction was completed. The mixture was diluted with ethyl acetate, filtered through a pad of Celite and the filtrate was washed with saturated NaHCO3, brine and dried over Na2SO4. The solvent was removed under reduced pressure and the crude product was purified by flash chromatography on silica gel, (20% ethyl acetate in hexanes) to afford 1.32 g (74%) of the title compound (67). 1H NMR (CDCl3, 400 MHz): δ 2.90 dd, J=14.4, 7.0 Hz, 1H), 3.20 (dd, J=14.4, 4.0 Hz, 1H), 3.70 (d, J=6.8 Hz, 1H), 5.35 (m, 1H), 7.28-7.11 (m, 5H), 7.53 (m, 2H), 7.65 (m, 1H), 7.93 (d, J=7.2 Hz, 2H).
