The palladium-catalyzed oxidation of alkyl enolethers to enals, which employs low loadings of a palladium catalyst, is described. The mild oxidation conditions tolerate a diverse array of functional groups, while allowing the formation of di-, tri-, and tetrasubtituted olefins. The application of this methodology to intramolecular reactions of alkyl enolethers containing pendant alcohols provides
The Ni(0)-catalyzed cross-coupling of alkenyl methylethers with boronicesters is described. Several types of alkenyl methylethers can be coupled with a wide range of boronicesters to give the stilbene derivatives.
