A general protocol for the synthesis of α-amino-α- alkyl phosphonic acids in either enantiomeric form is described based on the alkylation of chiral bicyclic phosphonamides derived from (R,R)- and (S,S)-1,2-diaminocyclohexane.

Pure diasteriomers, obtained simply and directly by reaction of hypophosphorous acid salts of (R)(+) or (S)(−) - N-α-methylbenzylamine with aldehydes, can be simultaneously deprotected and oxidised in one step to provide a highly convenient synthesis of α - aminophosphonic acids in high optical purity.

Stereoselective opening of homochiral acetals (2a-c) with triethyl phosphite was applied to the enantioselective synthesis of phosphono alcohols (1a-c), which were successfully converted to the alpha-amino phosphonic acid diethyl esters (6a-c).
