H makes a difference! A novel reactivity profile of propargyl vinyl ethers has been developed, which is controlled by the presence of a hydrogen atom at the homopropargylic position (see scheme; EWG=electron‐withdrawing group). This strategy was conveniently used to construct multifunctionalized phenolic platforms, including salicylaldehydes and the corresponding ketone derivatives.
