Three in one: The exocyclic β‐bromo enolether is a synthetically useful functional moiety in the preparation of functionalized oxygen heterocycles. A new tandem method for the synthesis of this valuable moiety has been achieved by employing silyl‐protected acetylenicalcohols. To demonstrate the synthetic potential of the developed method, a brief total synthesis of pachastrissamine was successfully
