Asymmetric synthesis of cis-5-substituted pyrrolidine 2-phosphonates using metal carbenoid NH insertion and δ-amino β-ketophosphonates

(Chemical equation presented) Cis-5-substituted pyrrolidine phosphonates, proline surrogates, are prepared by a highly stereoselective intramolecular metal carbenoid N-H insertion from a sulfinimine-derived δ-amino α-diazo β-ketophosphonate.
