Palladium‐catalysed <i>O</i>‐Allylation of α‐Hydroxyphosphonates: An Expedient Entry into Phosphono‐oxaheterocycles

Abstract

Abstract 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. magnified image
