An efficient and operationally simple domino Wacker-Heck reaction of allylic phenols and,-unsaturated ketones as well as esters in the presence of catalytic amounts of Pd(TFA)2 and an oxidant for the synthesis of 2,3-dihydro-benzo[1,4]dioxins and 2,3-dihydrobenzo[1,4]oxazins is described. The necessary substrates are prepared by monoallylation of catechol derivatives and ortho-aminophenol.
