                                Alkenylbutenolides were synthesized regioselectively in good to moderate yields from Baylis-Hillman adducts via a consecutive indium-mediated Barbier type reaction between Baylis-Hillman bromide and aldehyde, PCC oxidation of the homoallylic alcohol, double bond isomerization, and zinc-mediated Barbier type alkenylation protocol.
