Abstract
Ten previously unreported dipeptides ontaining aminobenzylphosphonic acid were prepared by carbodiimide method. These are; Glycyl-dl-1-aminobenzylphosphonic acid, alanyl-dl-1-aminobenzylphosphonic acid, L-alanyl-dl-1-aminobenzylphosphonic acid, N-phthalyl-L-phenylalanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxyglycyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxyalanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxy-L-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester, glycyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide, alanyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide and L-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide. The first six compounds were characterized, and the last four compounds were obtained in the crude state.
Aminobenzylphosphonic acid를 포함하고 있는 dipeptide들의 합성을 carbodimide법으로 시도하여 다음과 같은 새로운 화합물들을 얻었다. Glycyl-dl-1-aminobenzylphosphonic acid, alanyl-dl-1-aminobenzylphosphonic acid, L-alanyl-dl-1-aminobenzylphosphonic acid, N-phthalyl-L-phenylalanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxyglycyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxy-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester, N-carbobenzoxy-L-alanyl-dl-1-aminobenzylphosphonic acid diethyl ester, glycyl-dl-1-aminobenzylphosphonic acid diethyl ester hydobromide, alanyl-dl-1-aminobenzylphosphonic acid diethyl ester hydrobromide 및 L-alanyl-dl-1-aminobenzylphosphonic aciddiethyl ester hydrobromide.
