Umpolung in allylic phosphonates. Regio- and stereo-selective synthesis of (E)-γ-amino-α,β-unsaturated phosphonates by palladium-catalysed reaction of allylic acetoxy phosphonates

γ-Amino-α,β-unsaturated phosphonates have been synthesized regio- and stereo-selectively in high yield by the reaction of allylic α-acetoxy phosphonates with secondary amines catalysed by palladium.
