Palladium-catalysed O -Allylation of α-Hydroxyphosphonates: An Expedient Entry into Phosphono-oxaheterocycles
Résumé
We report here an unprecedented palladium‐catalysed O‐allylation of α‐hydroxyphosphonates. The method was eventually included in a sequential Pudovik/Tsuji‐Trost type O‐allylation/Ring‐Closing Metathesis to afford a variety of phosphorylated heterocycles of various sizes ranging from 5 to 16 starting from readily available aldehydes.
