[3+2] Cycloaddition of azide groups of N,N′-bis(4-azidofurazan-3-yl)methylenediamine to 1,3-dicarbonyl compounds and malonodinitrile was shown to proceed regioselectively with the formation of the corresponding N,N′-bis[4-(1H-1,2,3-triazol-1-yl)furazan-3-yl]methylenediamine derivatives. The reactions of N,N′-bis(4-azidofurazan-3-yl)methylenediamine with cyanoacetic acid ethyl ester and amide led to the formation of the product of transformation of the azide group in the starting compound to the amino groups.
N,N'-双(4-叠氮呋喃-3-基)亚甲基二胺的叠氮基团与1,3-二羰基化合物和丙二腈的[3+2]环加成反应可区域选择性地进行,形成相应的N,N' -双[4-(1H-1,2,3-三唑-1-基)呋喃-3-基]亚甲基二胺衍生物。 N,N'-双(4-叠氮呋喃-3-基)亚甲基二胺与氰基乙酸乙酯和酰胺的反应导致起始化合物中的叠氮基团转化为氨基的产物的形成。
