1-Nitronaphthalene, 2-nitronaphthalene and 1,3-dinitronaphthalene react with Danishefsky diene as normal electron demand Diels–Alder dienophiles to give hydroxyphenanthrene derivatives as principal products in reasonable yields. The aromatization is an expected behavior in thermal reactions involving nitro-substituted compounds. However, it was possible to isolate the primary cycloadducts when using
1-硝基萘,2-硝基萘和1,3-二硝基萘与Danishefsky二烯反应,这是正常的电子需求。Diels-Alder二烯亲和体以合理的收率得到羟基菲衍生物作为主要产物。芳香化是涉及硝基取代化合物的热反应中的预期行为。但是,使用1,3-二硝基萘时,虽然产率很低,但仍可以分离出初级环加合物。其他反应性较低的二烯不进行环加成反应。
