Adding an aryne to a tertiary allylamine affords o‐allylaniline products of an aza‐Claisenrearrangement. The aryne simultaneously provides the π component for the rearrangement and the quaternization event that lowers the activation energy for the sigmatropic shift. The reaction was applied to the synthesis of medium‐ring benzannulated amines (see scheme).
