The synthesis of a new pentacovalent oxaphospholene from a dienone, and its use as an enolate equivalent in the approach toward the syntheses of a phosphonate analog of sphingomyelin, sphingosine 1-phosphate and ceramide1-phosphate is described. Condensation of the new P(V) reagent with an azodicarboxylate, followed by reduction of the ketone produced cis- and/or trans-oxazolidinones, potential precursors
