combining the powerful twofold diene‐transmissive Diels–Alder chemistry of [3]dendralenes with the simplicity of enamine formation. On mixing at ambient temperature, a simple dienal condenses with a primary or secondary amine to generate the enamine, a 1‐amino‐[3]dendralene in situ, and this participates as a double diene in a sequence of two Diels–Alder events with separate dienophiles. Overall, four
1-氨基十氢化萘是由无环前体通过将[3]树枝状二烯的强大的二烯烃-透射性Diels-Alder化学方法与简单的烯胺形成相结合而制得的。在环境温度下混合时,简单的二烯与伯胺或仲胺缩合生成原位烯胺,即1-氨基-[3]树枝状烯,并以双二烯的形式参与两个Diels-Alder事件的发生。分开的双亲物。总体上,形成四个CC键和一个CN键。通过密度泛函理论计算,提供了对这些反应的力学见解。
