    • 2O, may be assigned to H-l. The signal at δ3.28 (1H, dd, J 3.2, 11.0 Hz), which collapses to a sharp doublet (J 11.0 Hz) on irradiation at δ5.35, may be assigned to H-2. From the size of the coupling constants, it appears that H-1 is equatorially disposed and that H-2 and H-3 are both axially disposed.
