reaction but omitting the acetic anhydride usually present in the reaction mixture. From these amines, through the thermal cyclization of their corresponding ethyl carbamates, a new access to the benzo[c]phenanthridin-6(5H)-ones was found. Preparation of water-soluble Nitidine and O-Methyl Fagaronine analogues bearing an alkylamino side chain on the C-6 position was achieved from these compounds.
以前未报道的2-芳基-
1-萘胺是通过使用Semmler-Wolf反应从2-芳基-1-四
酮肟中以高收率获得的,但省略了通常存在于反应混合物中的
乙酸酐。从这些胺中,通过它们相应的
氨基甲酸乙酯的热环化反应,发现了一种新的
苯并[c]
菲咯啶-6(5H)-
酮。由这些化合物可制备在C-6位带有烷基
氨基侧链的
水溶性亚硝啶和O-
