The [2,3] sigmatropic rearrangement of N-benzyl-O-allylhydroxylamines

Davies, Stephen G.,Fox, John F.,Jones, Simon,Price, Anne J.,Sanz, Miguel A.,Sellers, Thomas G. R.,Smith, Andrew D.,Teixeira, Fatima C.

, p. 1757 - 1765 (2007/10/03)

The rearrangement of a range of N-benzyl-O-allylhydroxylamines to the corresponding N-allylhydroxylamines upon treatment with n-BuLi in THF, followed by reduction to the corresponding N-allylamines, is described. Mechanistic studies of the transformation are consistent with an intramolecular [2,3] sigmatropic rearrangement.
