An improved method for the synthesis of 1-aminosubstituted benzyl phosphonic and -phosphinic acids under mild conditions is described. It consists of the reaction of diphenoxy chlorophosphine (1) or dichlorophenylphosphine (6) with substituted benzaldehydes 2 and a phosphoramidate 3 in the presence of a Lewis acid, followed by selective cleavage of the protective group of the resultant 1-(phosphorylamino)-substituted benzylphosphonate 4 or phosphinate 7, 9. A tentative reaction mechanism is postulated.

Dextrorotatory 1-amino-3',4'-dichlorobenzylphosphonic acid was found to be a potent inhibitor of the plant enzyme phenylalanine ammonia-lyase both in vitro and in vivo from among the ring-substituted 1-aminobenzylphosphonic acids and other analogues of phenylglycine. A structure activity relationship analysis of the results obtained permits predictions on the geometry of the pocket of the enzyme and is a basis in the strategy of better inhibitor synthesis.

Acid hydrolyses of 0,0-dimethyl or 0,0-diethyl 1-(diphenylmethylamino) benzylphosphonate intermediates 2, formed from the addition at elevated temperature of dimethyl or diethyl phosphite to benzylidenediphenylmethylamines 1, generates 1-aminobenzylphosphonic acids 3 in good yield.
