title: Biologically active halophthaloylpeptides. I. Synthesis of tetrachlorophthaloylamino acids and dipeptide derivatives.
abstract: The synthesis of a series of tetrachlorophthaloylamino acids and some of the corresponding methyl esters is described. Coupling of tetrachlorophthaloylamino acids with amino acid methyl esters by the N,N'-dicyclohexylcarbodiimide method yielded the desired tetrachlorophthaloyldipeptide methyl esters. All of the synthesized tetrachlorophthaloylamino acids, esters and some dipeptide methyl esters were found to be active against a number of microorganisms.
