A modified three-component condensation of 2-haloalkanamides, benzaldehydes and dialkyl phosphites leading to α-(2-haloacylamino)-substituted dialkyl benzylphosphonates 1 is described. Compounds 1 upon reaction with phthalimide and potassium carbonate under phase transfer catalysis conditions afford protected phosphonodipeptides, which can be used as important intermediates for the synthesis of oligophosphonopeptides.
