An electrophile-induced rearrangement of propargylic esters without need of transition catalysis is possible. In particular, this observation provides a mild, economic, and effective method for the introduction of benzyl ether derivatives to access functionalized α,β-unsaturated ketones. Preliminary mechanistic studies suggest that this rearrangement undergoes an intramolecular 1,3-acyloxy shift.
