Abstract
Methyl N-(2-(benzoylamino)benzoyl)-2-aminoalkanoates 4a-d were efficiently prepared by DCC coupling of 2-benzoylamino-benzoic acid 1 with amino acid methyl esters; or alternatively by reaction of amino acid esters with 2-phenyl-4H-benzo(d)(1,3)oxazin-4-one (2). Dipeptides 7a-k were subsequently prepared following the azide-coupling method from esters 4.
