A transition-metal free synthetic strategy has been developed for the direct synthesis of ortho-formyl substituted allyl aryl ethers via a cascade three-component coupling of arynes, activated alkene and N,N-dimethylformamide. The reaction proceeds via C–O and C–Cbond cleavage as well as C–C and two new C–Obond formations in a single reaction vessel. The methodology provides a good yield of ortho-formyl
