2-amino-4-trideuteriomethyl-pyrimidine and showing total deuterium incorporation at one of the olefinic carbons and partial deuterium incorporation para to the amino group, served to assign 13C and 1H resonances in the condensation products 3. The nature of the species undergoing condensation has been inferred from labelling experiments and from 1H and 13C nmr spectra of precursors and products in dimethylsulfoxide
得到的产物将1-甲基-5-硝基咪唑-2-醛与2-氨基-4-三叔甲基甲基-嘧啶缩合,并显示出在一个烯属碳原子上的总氘掺入和对氨基的部分氘掺入,可用于指定13缩合产物中的C和1 H共振3.从标记实验以及前体和产物在二甲亚砜和三氟乙酸中的1 H和13 C nmr光谱推断出正在进行缩合的物质的性质。
