alkylation followed by a Pd-catalyzed direct C-H arylation to obtain a series of potentially bioactive 4-phenyl-4,5-dihydro-6H,8H-pyrido[3,2,1-de]phenanthridin-6-one derivatives 4a-f in good yields. Finally, the toxicological profile of the prepared final compounds, including their corresponding intermediates, was explored through in silico computational methods, while the acute toxicity toward zebrafish
报道了新型吡啶并 [3,2,1-de]phenanthridin-6-ones 的快速、高效和原始合成。首先,关键的肉桂酰胺中间体 8a-f 很容易由商业取代的苯胺、肉桂酸和 2-溴苄基溴在串联酰胺化和 N-烷基化方案中制备。然后,将这些 N-芳基-N-(2-溴苄基) 肉桂酰胺 8a-f 进行 TFA 介导的分子内 Friedel-Crafts 烷基化,然后进行 Pd 催化的直接 CH 芳基化,以获得一系列具有潜在生物活性的 4-苯基- 4,5-dihydro-6H,8H-pyrido[3,2,1-de]phenanthridin-6-one 衍生物 4a-f,产率高。最后,通过计算机计算方法探索了制备的最终化合物(包括其相应的中间体)的毒理学特征,而对斑马鱼胚胎的急性毒性(96 hpf-LC50,
