  Isolation, structure characterization and conformational analysis of a unique 4α,9α-epoxysteroid sulphate from the okinawan ophiuroid Ophiomastix annulosa

  摘要：

  A new 5-beta-steroid disulphate (1), with a unique 4-alpha,9-alpha-ether bridge, has been isolated from the ophiuroid Ophiomastix annulosa, together with the minor related compound 2 and the known 3 and 4. The structures of 1 and 2 were deduced mainly from FAB-MS and NMR data. The lowest energy conformation of the desulphated 1a, obtained by Molecular Mechanics calculations in the force field MM2, completely agrees with the H-1-NMR data.
