Ethyl 3-(2-pyridyl)-2H-azirine-2-carboxylate, the first example of an 3-heteroamatic 2H-azirine has been prepared. The re- action of ethyl 3-(2-pyridyl)-2H-azirine-2-carboxylate with conju- gated 1,3-dienes, under mild conditions and in the absence of Lewis acid catalyst, afforded cycloadducts in good yield and high stereo- selectivity.
制备了 3-(2-吡啶基)-2H-azirine-2-carboxylate 乙酯,这是 3-杂环 2H-azirine 的第一个例子。3-(2-吡啶基)-2H-氮杂环丙烷-2-甲酸乙酯与共轭 1,3-二烯在温和条件下和没有路易斯酸催化剂的情况下反应以良好的收率和高立体选择性。
