非金屬催化劑催化合成苯重氮基
Abstract
本實驗目的在於探討合成1,5-benzodiazepine類化合物的合成反應。
經由使用各種起始物,包括胺類(diamines) 1a-c及酮類(ketones)2a-k的羰基化合物為反應物。反應系統分別使用以三種不同的催化試劑,包括2,4,6-trichloro-1,3,5-triazine (TCT)、 p-toluenesulponic acid (PTSA)、35% hydrogen chloride solution (35% HCl(aq))、在室溫且使用MeOH為溶劑的條件下,催化上述二種成分間的加成反應。反應結果發現在此反應條件下我們可以得到一系列高產率之1,5-benzodiazepine類化合物產物。因為,此類化合物皆為具有氮的異原子環狀化合物,在藥物化學以及生物化學方面都有重要的研究價值,因此值得我們繼續在這個領域做研究。
1,5-benzodiazepines can be sythesis by using ketones and diamines in the present of the different catalysts, trichloro-1,3,5-triazine (TCT), p-toluenesulfonic acid (PTSA), or 35% HCl solution in the MeOH at room temperature. We have developed this method that can afford high yields of prodcts and simple to do compared to traditional methods.
