Palladium(II)-catalyzed direct alkenylation of dihydropyranones.
A palladium(II)-catalyzed direct alkenylation reaction of dihydropyranones was developed. Various substituted dihydropyranones could afford the desired products in reasonable yields. And different acrylates were found to be good coupling partners in this coupling reaction. A Pd(0)/Pd(II) catalytic pathway was proposed to be involved in this coupling reaction.
