Consecutive alkene cross-metathesis/oxonium ylide formation-rearrangement: synthesis of the anti-HIV agent hyperolactone C.
Alpha-diazo-beta-ketoesters bearing allylic ether functionality undergo highly stereoselective Ru-carbene-catalyzed alkene cross-metathesis followed by Rh(2)(OAc)(4)-catalyzed oxonium ylide formation/[2,3] sigmatropic rearrangement in a one-flask operation and in a highly diastereoselective manner....
