Quinine was used as a 31P NMR shift reagent for the determination of the enantiomeric excess of diethyl 1,2-dihydroxyethanephosphonates obtained either by chemical or biocatalytic synthesis. Sharpless asymmetric dihydroxylation of diethyl trans

Unsaturated phosphonate esters (1) have been subjected to osmium tetroxide catalyzed asymmetric dihydroxylation (AD) using dihydroquinidine and dihydroquinine derivatives as chiral ligands to furnish the optically active diols (2) which have been converte
