The synthesis of 1-aminobenzylphosphonic acids from benzylidenediphenylmethylamines, for use as structural units in antithrombotic tripeptides
摘要:
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.
