Reaction Steps

To a stirred solution of (1R,3S)-3-tetrahydropyranyloxycyclopentanol (2.00 g, 10.7 mmol), phenol (1.20 g, 12.0 mmol) and triphenylphosphine (3.20 g, 12.0 mmol) in dry THF (40 ml) cooled to 0° C. was added dropwise a solution of diethyl azodicarboxylate (2.60 g, 15.0 mmol) in dry THF (10 ml). The mixture was stirred for 1 h at room temperature and then the volatiles removed under reduced pressure. Chromatographic purification of the residue {SiO2, 150 g; hexane/ethyl acetate (20:1)} provided 2.16 g (77 %) of the title compound as a colorless oil: 1H NMR δ7.33-7.22 (m, 2H), 6.99-6.83 (m, 3H), 4.98-4.81 (m, 1H), 4.70-4.60 (m, 1H), 4.55-4.41 (m, 1H), 4.00-3.85 (m, 1H), 3.58-3.47 (m, 1H), 2.30-1.45 (m, 12H).
