Abstract

NEW MATERIAL:A sesquiterpene derivative of formula I.
USE: An intermediate for Warburganal (Warburganal, an effective antifeedant against armyworm).
PREPARATION: An 7-oxoisodrimenin of formula II is treated and refluxed with a dihydric alcohol, e.g. ethylene glycol, and an organic acid, e.g. p-toluenesulfonic acid, to give a ketal of formula III. The resulting ketal is reacted with a reducing reagent, e.g. lithium aluminum hydride, in an organic solvent, to obtain a ketone of formula IV, and further this ketone is reacted with an acetylating agnet, e.g. acetic anhydride-pyridine, in a solvent, to produce a diacetate of formula V, which is finally treated with a peroxide, e.g. H2O2, in the presence of an aqueous alkali, to produce the epoxide of formula I.
