A TOTAL SYNTHESIS OF (±)-WIDDROL. SYNTHETIC APPLICATION OF THE FORMAL BRIDGEHEAD SUBSTITUTION OF 1-METHOXYBICYCLO[3.2.2]NON-6-EN-2-ONES WITH ALKYL GROUPS

Abstract
The [6–7] fused-ring sesquiterpene (±)-widdrol has been prepared stereospecifically utilizing the characteristic reactions of the bridged polycyclic compounds derived from 1-methoxy-5-methylbicyclo[3.2.2]non-6-en-2-one.
