A successive route for the synthesis of substituted dibenzo[a,e]cycloheptatriene 1 was established by the reduction of 2-allylbenzaldehyde 4, the BF3·OEt2-mediated intermolecular coupling of 2-allylphenylmethanol 5 with oxygenated benzenes 6, the olefinic oxidative cleavage of 7 and the intramolecular ring-closure of 8. Functionalized anthracene 13 were prepared from 2-vinylbenzaldehyde 9. The key
通过还原2-烯丙基甲醛4,BF 3 ·OEt 2介导的2-烯丙基苯基甲醇5与氧化苯6的分子间偶联,烯烃的氧化反应,建立了取代二苯并[ a,e ]环庚三烯1的连续合成路线。裂解7和8的分子内闭环。从2-乙烯基苯甲醛9制备官能化的蒽13。通过X射线单晶衍射分析确认了关键结构。
