Dynamic kinetic resolution driven, asymmetric transfer hydrogenation reactions of a wide range of 2-substituted α-alkoxy-β- ketophosphonates 3 were observed to proceed efficiently to give the corresponding 2-substituted α-alkoxy-β-hydroxy phosphonates 4 w

Asymmetric dihydroxylation (AD) of 1(E)-alkenylphosphonates with an AD- mix-α or -β reagent was examined to give a series of optically active threo-α,β-dihydroxyphosphonates. Good enantioselectivity (>88% ee) was observed in the AD reaction of 1(E)-alkenylphosphonates with conjugated aromatic substituents. The steric effects of the ester functionality in the course of the dihydroxylation were also evaluated. Enantioselectivity and yield were significantly improved when the AD reaction was carded out with dimethyl phosphonate instead of diethyl phosphonate.

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
