Amino keto-2,7-dienes undergo ring-closing metathesis (RCM) to give 4-aminocyclopentenones, valuable intermediates in the asymmetric construction of carbocyclic nucleosides. The key amino ketodienes were prepared using δ-amino β-ketophophonates, a new sul

(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.
