Biotransformation of Olivetol by Syncephalastrum racemosum

Abstract
A study of the biotransformation of olivetol by S. racemosum ATCC 18192 led to the isolation of 3 metabolites, which were identified as 4''-hydroxyolivetol, 3-(3,5-dihydroxyphenyl)-1-propanol and 3-(3,5-dihydroxyphenyl)-1-propanoic acid. The structures of the isolated metabolites were deduced by comparison of their spectral properties (PMR, CMR [carbon magnetic resonance], MS [mass spectrometry] with those of olivetol. The absolute configuration of 4''-hydroxyolivetol was determined to be R by the Horeau partial resolution method. Biotransformation of olivetol therefore appears to occur by a subterminal oxidation process.
