The synthesis, characterization, and a study of the cycloaddition reactions of 5-nitro-1,2,3-triazine (3) are reported. The electron-deficient nature of 3 permits rapid cycloaddition with a variety of electron-rich dienophiles, including amidines, enamines, enol ethers, ynamines, and ketene acetals in high to moderate yields. 1H NMR studies of a representative cycloaddition reaction between 3 and an
报道了5-硝基1,2,3-三嗪(3)的合成,表征和环加成反应的研究。的缺电子的性质3只允许快速环加成与各种富电子亲双烯体,包括脒,烯胺,烯醇醚,ynamines和烯酮缩醛在高至中等产率的。1与3和an之间的代表性环加成反应的1 H NMR研究显示出显着的反应速率和效率(1 mM,<60 s,CD 3 CN,23°C,> 95%)。
