The NMR spectrum of oxodendrobinediol monoacetate (V),a degradation product of dendrobine (I),showed a quartet, corresponding to the C6 proton (4.87τ,J1=3.5 c.p, s.,J2=9.0 c.p.s.),among which the larger value of 9.0 c.p.s.should arise Erom the interaction between vicinal protons at C5 and C6, implying a dihedral angle of about 180° between them.
