N-Carbamoylamino acids were obtained through the alkylation of monosubstituted parabanic acids followed by hydrolysis of the intermediate products. This new methodology furnishes structurally and functionally diverse N-carbamoylamino acids in high preparative yields and excellent purity.

the resulting products. Using this model substrate, the products formed during the peroxynitrite reaction were identified as the ethyl derivatives of oxaluric acid, 5-iminoimidazolidin-2,4-dione, III, [N-nitro-N'-[2,4-dioxo-imidazolidine-5-ylidene]-urea, V, dehydroallantoin, parabanic acid, cyanuricacid, and uricacid. Upon the basis of the previous studies with 8-oxodG, these products were recognized
