Marine sterols. 27. 25-hydroxy derivative of sarcosterol, a novel marine sterol with a 23-methyl and a 17(20)E-double bond, from the soft coral Sinularia mayi
摘要:
The dihydroxysterol, isolated from the soft coral Sinularia mayi of Okinawa, was shown by spectroscopic data and chemical conversion to be (23R, 24S)-23,24-dimethylcholesta-5,17(20)E-diene- 3 beta,25-diol (25-hydroxysarcosterol).
