Selective Reduction of Amino Allenephosphonates: Preparation of α‐Amino Vinylphosphonates

Abstract

Abstract α‐Amino vinylphosphonates were prepared by chemo‐ and stereoselective reduction of α‐amino allenephosphonates. Our results showed that the substituents on the allene, phosphonate, and nitrogen moieties affected the stereoselectivity of the reduction. Z ‐α‐Amino vinylphosphonates were prepared with good selectivities up to > 95:5.
