“Diazo” not needed: The title reaction results in the rearrangement of oxonium ylides, which were prepared from readily available homopropargylic allylic ethers instead of diazo compounds, through two different mechanisms: a concerted 2,3‐sigmatropic rearrangement, or a stepwise 1,4‐allyl migration followed by a Claisen rearrangement (see scheme).
