The reactions of HNO3 with tetrahydro-1,3-oxazines 1a—c produced by aminomethylation of diketopiperazine, isatin, and succinimide, respectively, afforded nitrates of amino alcohols [RCH2NH2(CH2)3ONO2]+NO3– (4a—c) whose subsequent N-nitrosation (NaNO2, AcOH) gave nitrates of N-nitrosoamino alcohols RCH2N(NO)(CH2)3ONO2 (5a—c). The structures of compound 5b,c were established by X-ray diffraction analysis
HNO3 与分别由二酮哌嗪、靛红和琥珀酰亚胺的氨甲基化产生的四氢-1,3-恶嗪 1a-c 反应,得到氨基醇的硝酸盐 [RCH2NH2(CH2)3ONO2]+NO3-(4a-c),其随后的N-亚硝化(NaNO2,AcOH)得到 N-亚硝基氨基醇的硝酸盐 RCH2N(NO)(CH2)3ONO2 (5a-c)。化合物5b、c的结构通过X射线衍射分析确定。
