Abstract

PURPOSE: To obtain a fragrolide useful as an intermediate for antifeedants of an African army worm, etc., by oxidizing 6-hydroxylactone derivative prepared from an l-abietic acid as a starting material, etc.
CONSTITUTION: A 6-hydroxylactone derivative shwon by the formula I is oxidized, preferably through Jones oxidation to give a fragrolide shown by the formula II. The oxidation is carried out using an oxidizing agent, e.g., a Jones reagent, or chromic acid-pyridine, etc. to give a compound shown by the formula II approximately quantitatively. The compound shown by the formula I can be obtained from an l-abietic acid shown by the formula III, the main component of the resins of pine and oak trees. An agandencidial shown by the formula IV having strong antifeedant action on an African army worm can be obtained from the compound shown by the formula II.
