description	In the zone: The use of vinylogous aza‐enamaines (hydrazones) as a source of an alkenyl group has been achieved (see scheme). Unmasking of the aza‐enamine moiety opens up a novel approach for the preparation of chiral allylic amines bearing an electron‐withdrawing alkene moiety functionalized at the electron‐deficient β position.
