)‐N'‐nitrosocarbamoyl]amino acid amides and esters as potential antineoplastic substances are reported. N‐[N'‐(2‐chloroethyl)‐N'‐nitrosocarbamoyl]amino acids (with the exception of the glycine derivative) were prepared by reaction of 2‐chloroethyl isocyanate with the sodium salt of an amino acid in a heterogenous medium followed by nitrosation with sodium nitrite under acidic conditions. Condensation
报道了 N-[N'-(2-氯乙基)-N'-亚硝基氨基甲酰基]氨基酸酰胺和酯作为潜在抗肿瘤物质的合成。N-[N'-(2-氯乙基)-N'-亚硝基氨基甲酰基]氨基酸(甘氨酸衍生物除外)是通过异氰酸2-氯乙基酯与氨基酸的钠盐在异质介质中反应制备的,然后在酸性条件下用亚硝酸钠亚硝化。使用 1,1-羰基二咪唑与胺或醇缩合生成酰胺或酯。
