Diastereomeric diethyl (1R,2R)- and (1S,2R)-2,3-epoxy-1-benzyloxypropylphosphonates were obtained from the respective 2,3-O-cyclohexylidene-1-hydroxypropylphosphonates via the following sequence of reactions: benzylation, acetal hydrolysis and transformation of the terminal diol into the epoxide using the Sharpless protocol. These epoxides were regioselectively opened with dibenzylamine to afford the
