A novel route has been devised for the preparation of a series of 1-aminoalkylphosphonate diesters, precursors to analogues of a-amino acids. The route involves a facile bromine substitution at the 1-position of alkylphosphonate diesters using N-bromosuccinimide, followed by azide ion displacement and catalytic hydrogenolysis.

Chiral phosphine-containing skeletons play a pivotal role in bioactive natural products, pharmaceuticals, chiral catalysts, and ligands. Despite considerable progress has been made in the synthesis of chiral phosphorus compounds, the development of facile and modular methods to access chiralallylic phosphorus compounds remains challenging due to the simultaneous control required for reactivity, enantioselectivity
