Nitration of N-(ω-acylamino0-β,β-dinitroalkyl)tetrahydro-1,3-oxazines and N-(ω-acylamino-β,β-dinitroalkyl)oxazolidines resulted in O-nitrates bearing amide, dinitromethylene, and nitroamine groups. It was found that nitration can be accompanied by N-hydroxymethylation of the amide group. Three nitrates synthesized were tested for, and exhibited good level of, cardioprotection.
N-(ω-acylamino0-β,β-dinitroalkyl)tetrahydro-1,3-oxazines 和 N-(ω-acylamino-β,β-dinitroalkyl)oxazolidines 的硝化反应产生了带有酰胺基、二硝基和
硝胺基的 O-
硝酸盐。研究发现,硝化作用可能伴随着酰胺基团的 N-羟甲基化。对合成的三种
硝酸盐进行了心脏保护测试,结果表明它们具有良好的心脏保护作用。
