Abstract A series of new 2‐amino‐3‐cyano‐4‐aryl‐1,4,5,6‐tetrahydrobenzo[h]chromenes derivatives were synthesized by the reaction of malononitrile with 2‐arylmethylidene‐3, 4‐dihydro‐1(2H)‐naphthalenone in N,N‐dimethylformamide (DMF) at 80°C catalyzed by KF‐Al2O3. The structure of the product was confirmed by x‐ray analysis.
摘要 通过丙二腈与 2-芳基亚甲基-3, 4-二氢-1 反应合成了一系列新的 2-氨基-3-氰基-4-芳基-1,4,5,6-四氢苯并[h]色烯衍生物。 (2H)-萘酮在 N,N-二甲基甲酰胺 (DMF) 中在 80°C 下由 KF-Al2O3 催化。X射线分析证实了产物的结构。
