Abstract

By fractional crystallization D-mandelic acid salt of diethyl-dl-1-aminobenzylphosphonate prepared from benzaldehyde, diethylphosphite and ammonia at the atmospheric pressure, gave diethyl(-)-1-aminobenzylphosphonate. (+)-1-Aminobenzylphosphonic acid was obtained by acidic hydrolysis of diethyl(-)-1-aminobenzylphosphonate hydrochloride.
