Synthesis of ambrettolide from phloionolic acid
Abstract
The synthesis of ambrettolide (cis-hexadec-7-enolide) and its trans-stereoisomer is accomplished from threo-9,10,18-trihydroxyoctadecanoic acid (phloionolic acid derived from cork)via a high-yielding seven-stage synthesis. Since phloionolic acid has recently been obtained from cork in reasonable yield, the latter may be a commercial starting material for the preparation of ambrettolide.
