(±)-Phoracantholid I via the caesium carbonate-promoted ring closures of the methanesulphonate of 9-hydroxydecanoic acid
Abstract
(±)-Phoracantholid I, a product from the secretion of the longicorn Phoracantha synonyma, has been synthesised via the caesium carbonate treatment of the methanesulphonate of 9-hydroxydecanoic acid, prepared from the easily accessible 9-oxo-derivative.
