A simple method for the synthesis of esters of tosyloxymethylphosphonic acid based on the adamantane series of alcohols and diethyl tosyloxymethyl phosphonate was developed. The di(adamantylalkyl) and di(adamantyloxyalkyl) tosyloxymethylphosphonates are of interest as key compounds in the synthesis of antiviral drugs of the nucleoside phosphonate class.
