Abstract
(3S, 8E)-1,3-Dihydroxy-8-decen-5-one, a Metabolite of Streptomyces fimbriatus (MILLARD and BURR 1926) From the cultures of Streptomyces fimbriatus, strain Tu 2335, the title compound 1 was isolated by solvent extraction, chromatography, and distillation. Its constitution was determined by spectroscopic investigations of 1 and some of its derivatives, and the chirality by transformation to (R)-1,3-isopropylidenedioxy-decane (12); a reference sample of the latter was prepared from (R)-methyl 3-hydroxydecanoate (10). In the equilibrium mixture the keto form 1 predominates the two hemiacetals 2a and 2b. Compound 1 is inactive against bacteria, yeasts and fungi.
