A simple and convenient procedure has been developed for the construction of alpha-hydroxyketone phosphates via I2O5/DBU mediated direct alpha-phosphoryloxylation of ketones with H-phosphonates. This new reaction proceeds through three steps involving alpha-iodination of ketones, oxidation of H-phosphonates, and nucleophilic substitution of alpha-iodo ketones to access a series of alpha-hydroxyketone phosphates of biological importance.
