Abstract
Benzaldehyde, diethylphosphite와 암모니아를 상압에서 반응시켜 diethyl dl-1-aminobenzylphosphonate를 합성하였다. 이 화합물의 D-mandelic acid 염으로부터 diethyl (-)-1-aminobenzylphosphonate hydrochloride를 분리한 후 산으로 가수분해시켜 (+)-1-aminobenzylphosphonic acid를 얻었다.

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.
