Reaction of electron‐deficient alkenes with 3,3‐diaryl‐2‐propen‐1‐amines under the amide formation conditions gave the tricyclic compounds in sequential processes involving intramolecular Diels–Alder reaction. The reaction gave cis‐ and trans‐fused tricyclic compounds selectively, depending on the substituents on the benzene ring, reaction temperature and solvent.
在酰胺形成条件下,缺电子烯烃与3,3-二芳基-2-丙-1-胺的反应在分子内Diels-Alder反应的顺序过程中得到了三环化合物。该反应得到的顺式-和反式-融合三环化合物选择性,这取决于对苯环,反应温度和溶剂的取代基。
