Asymmetric Synthesis of Cis-5-Substituted Pyrrolidine 2-Phosphonates Using Metal Carbenoid NH Insertion and δ-Amino β-Ketophosphonates
摘要:
Cis-5-substituted pyrrolidine phosphonates, proline surrogates, are prepared by a highly stereoselective intramolecular metal carbenoid N-H insertion from a sulfinimine-derived delta-amino alpha-diazo beta-ketophosphonate.
