In connection with a total synthesis of echinulin and related alkaloids, acid-catalyzed amino-Claisen rearrangement of N-allylaniline (2), N, 2-diallylaniline (4), N, 2, 6-trially-laniline (7), and N, N-diallylaniline (5) was examined in refluxing xylene, in the presence of zinc chloride or boron trifluoride etherate. Boron trifluoride etherate was found to be more effective acid for this rearrangement.
