Abstract

PURPOSE: To obtain a 6-hydroxylactone derivative useful as an intermediate for antifeedants of an African army worm, etc., by hydrolyzing a 6-acetoxylactone derivative prepared from an l-abietic acid as a starting material.
CONSTITUTION: A 6-acetoxylactone derivative shown by the formula I as a starting material is hydrolyzed to give a 6-hydroxylactone derivative shown by the formula II. The hydrolysis is preferably carried out using K2CO3-H2O-CH3OH, KOH- CH3OH, etc. at room temperatures for 6W36hr. 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. A fragrolide shown by the formula IV, which has been already isolated as a natural substance, can be obtained from the compound shown by the formula II. An agandencidial shown by the formula IV having strong antifeedant action on an African army worm can also be obtained from the fragrolide.
