    No full text
    A method for the synthesis of N-phosphoroamino acids and peptides is described. Di-p-nitrobenzylphosphorochloridate or di-p-iodobenzylphosphorochloridate was coupled with esters of amino acids or peptides; this was followed by removal of the p-nitrobenzyl and p-iodobenzyl groups through catalytic hydrogenation in alcoholic alkaline medium. © 1955, American Chemical Society.
