The Synthesis and the Absolute Configuration of Phoracantholide I and J; The Defensive Secretion of the Eucarypt Longicorn,Phoracantha synonyma

Abstract
Both enantiomers of phoracantholide I and J were synthesized from a chiral starting material obtainable via yeast reduction, and the absolute configurations of the natural materials were determined by GLC studies using a chiral stationary phase.
