Syntheses of a series of new N, N-dialkylnitrosamines monosubstituted at the α-carbon with an acetoxy group were reported. They were prepared by the procedures reported earlier, but a new procedure was provided, according to which N-alkyl-N-(methoxymethyl)-nitrosamines were converted into N-alkyl-N-(acetoxymethyl) nitrosamines in low but satisfactory yield by refluxing them in acetic acid. The (E)-(Z) conformer ratios of these compounds determined by nuclear magnetic resonance measurement were given.
报告了一系列在 α 碳上用乙酰氧基单取代的新型 N,N-二烷基亚
硝胺的合成。根据该程序,N-烷基-N-(甲氧基甲基)亚
硝胺通过在
乙酸中回流转化为 N-烷基-N-(乙酰氧甲基)亚
硝胺,产量低但令人满意。通过核磁共振测量确定了这些化合物的(E)-(Z)构象比。
