Abstract
A one-pot reaction of allylic alcohols with tosyl isocyanate followed by palladium(II)-catalyzed allylic substitution gives N-tosyl (E)-allylic amines in high yield. The allylic substitution reaction occurs with high regio- and stereoselectivity only at the γ-position of the 1- or 3-substituted allylic alcohols.
