title: Marine sterols. XIII. Isolation and synthesis of 1 beta,3 beta,5,6 beta-tetrahydroxy-5 alpha-androstan-17-one from the soft coral Sarcophyton glaucum.
abstract: A new polyhydroxysterol 1 beta,3 beta,5,6 beta-tetrahydroxy-5 alpha-androstn-17-one (1) was isolated from the soft coral Sarcophyton glaucum. The structure of 1 was deduced from comparison of the spectral data with those of known 1 beta,3 beta,5 alpha,6 beta-tetrahydroxysterols and confirmed by the synthesis starting from 1 beta,3 beta-dihydroxy-5,16-pregnadien-20-one (6a).
