Synthesis of acyl derivatives of L-tryptophan containing residues of anthranilic and oxalic acids
摘要:
Oxamoyl derivatives of dipeptide, N-anthranoyl-L-tryptophan, were synthesized by acylation of L-tryptophan methyl ester hydrochloride with 3,1-benzoxazinone derivatives. A one-stage procedure was developed for the synthesis of esters of N-[2-(N'-R-amidooxalyl)aminobenzoyl]-L-tryptophan.
