Adding an aryne to a tertiary allylamine affords oallylaniline products of an aza-Claisen rearrangement. 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). © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
