(3S,5R,6E,8E)-Deca-6,8-diene-1,3,5-triol, a New Metabolite from Streptomyces fimbriatus (MILLARDet BURR 1926) The title compound 2, a new C10-metabolite related to the previously found (3S-8E)-1,3-dihydroxydec-8-en-5-one (1), was isolated from the culture filtrate of Streptomyces fimbriatus, strain Tu 2335 by solvent extraction and chromatography. The constitution and the absolute configuration were determined by spectroscopic methods and chemical derivatization. The relative configurations were determined by NOE measurements with the silyl-protected 3,5-isopropylidene derivative of 2.
