A catalyst-free [4 + 2] annulation process between in situ generated 1,2-diaza-1,3-butadienes and simple olefins has been developed. Under mild conditions, the reactions afforded 1,4,5,6-tetrahydropyridazines, which feature a wide range of bioactive compounds, with high yields (up to 99% yield).
已开发出一种原位生成的1,2-二氮杂-1,3-丁二烯与简单烯烃之间的无催化剂[4+2]环化反应过程。在温和条件下,该反应能以高收率(高达99%)得到具有多种生物活性化合物的1,4,5,6-四氢哒嗪。
