Highway to the hydrazone: A hypervalent iodide initiated cascade process enables the rapid union of an aldehyde, an allylic hydrazide, and an alcohol (see scheme; Pv=pivaloyl). This process affords a diverse range of functionalized ether adducts, while simultaneously generating a stereodefined alkene and two new vicinal stereocenters. The use of chiral non‐racemic hydrazines and alcohols offers a rapid
