title: Total synthesis of the novel bacterial fatty acid 16-methyl-8(Z)-heptadecenoic acid.
abstract: The recently discovered bacterial fatty acid 16-methyl-8(Z)-heptadecenoic acid was synthesized for the first time in four steps (22% overall yield) starting from commercially available 8-methylnonanoic acid. The synthetic approach provided enough material to corroborate the structure and stereochemistry of the acid, which was recently identified in a Micrococcus bacterium from Lake Pomorie in Bulgaria. Reference equivalent-chain length values in nonpolar capillary gas chromatography for methyl 16-methyl-8(Z)-heptadecenoate and methyl 16-methyl-8(E)-heptadecenoate are also reported. This information will be helpful in subsequent characterizations of these fatty acids, as well as in the total identification of the fatty acid profile of bacteria producing these compounds.
