The Stereochemistry of the Aryl Phosphate/Aryl Phosphonate Rearrangement in 1,3,2-Oxazaphospholidine 2-Oxides

Article abstract of DOI:10.1021/jo00311a017

On treatment with LDA/THF (aryloxy)phospholidines in the pseudoephedrine/ephedrine series undergo P-O to P-C rearrangement to afford arylphospholidines with retention of configuration at phosphorus.The stereochemistry of each product was assigned by 1H NM
