Abstract
Abstract Protection of the amino group of aminophosphonic and aminophosphonous acids with benzyl chloro-formate followed by esterification of the TV-protected derivatives with O-benzyl-N,N′-dicyclohexylo-isoureas is described. The esterification of aminobenzylphosphonic and aminobenzylphosphonous acids was studied in some details in order to discuss the scope and limitation of this procedure. The differences in the reactions of aminoalkylphosphonic and aminoalkylphosphonous acids are pointed out.
