Silyl enolates generated from α-allyloxy ketones afforded the [2,3]-Wittig rearrangement products in good to high yields in the presence of a catalytic amount of Lewis base such as lithium 2-pyrrol...
Lewis base-catalyzed [2,3]-Wittig rearrangement of silyl enolates generated from α-allyloxy carbonyl compounds is described. The [2,3]-Wittig rearrangement of silyl enolates generated from α-allylo...
