Reaction Steps

To a stirred solution of (1R,3S)-1-(tert-butyldimethylsilyl)oxy-3-tetrahydropyranyloxycyclopentane (11.3 g, 33.0 mmol) in dry THF (40 ml) was added a 1.0M solution of tetrabutylammonium fluoride in THF (50 ml, 50.0 mmol). After stirring for 1 h at room temperature, the reaction mixture was poured into water (200 ml) and the whole extracted with ether (200 ml). The ether phase was washed with brine (200 ml), dried (MgSO4) and concentrated under reduced pressure. Chromatographic purification of the residue {SiO2, 800 g; hexane/ethyl acetate (2:1) with 1% of triethylamine} provided 5.47 g (73%) of the title compound as a colorless oil: 1H NMR δ4.73-4.64 (m, 1H), 4.42-4.23 (m, 2H), 3.95-3.81 (m, 1H), 3.59-3.44 (m, 1H), 2.20-1.20 (m, 13H).
