  For the sake of establishment of a versatile synthetic method for benzo [c] phenanthridine alkaloids, improvement of the Robinson synthetic method was examined. Thirteen chalcones (7a-m) were prepared by condensation of two acetophenone derivatives (15 and 16) with eleven benzaldehyde derivatives (19a-k) as fundamental starting materials. Hydrocyanation of these chalcones (7a-l) except one (7m) gave the corresponding 2, 4-bisaryl-4-oxobutyronitriles (8a-l). Eleven 2, 4-bisaryl-4-oxobutyramides (9a-k) were also prepared.

  为了建立一种通用的苯并[c]菲啶生物碱合成方法，对Robinson合成方法进行了改进。通过将两个乙酰苯衍生物（15和16）与十一种苯甲醛衍生物（19a-k）缩合，制备了十三种查尔酮（7a-m）作为基本起始材料。除了一个查尔酮（7m）外，这些查尔酮（7a-l）的氰化反应得到了相应的2,4-双芳基-4-氧代丁腈（8a-l）。还制备了十一种2,4-双芳基-4-氧代丁酰胺（9a-k）。

  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-甲基法加罗宁类似物。

  The synthetic pathway from 2, 4-bisaryl-4-oxobutyramide (3) to 2-aryl-1-tetralone (4), which is the key intermediate in the Robinson synthesis of antitumor-active benzo [c] phenanthridine alkaloids was improved. Treatment of the model keto-amide (3a) under the reported basic conditions gave a γ-keto-α, β-unsaturated acid (9) and degradation products. Reduction of the 2, 4-bisaryl-4-oxobutyramide (3) with sodium borohydride gave 2, 4-bisaryl-4-hydroxybutyramide (16), which could easily be hydrogenolyzed to give 2, 4-bisarylbutyramide (15). However, this transformation also tended to give a γ-lactam derivative (17), unfortunately. We succeeded in the direct hydrogenolysis of the 2, 4-bisaryl-4-oxobutyramide (3) to the 2, 4-bisarylbutyramide (15), which could be hydrolyzed to the corresponding acid (5) without difficulty. The direct hydrolysis of the 2, 4-bisaryl-4-oxobutyronitrile (2) to the 2, 4-bisaryl-4-oxobutyric acid (6) as reported by Cheng et al. was also examined. Ten 2-aryl-1-tetralones (4) required as starting materials for syntheses of various benzo [c] phenanthridine alkaloids were prepared.

  从 2，4-二芳基-4-氧代丁酰胺（3）到 2-芳基-1-四氢萘酮（4）的合成途径得到了改进，而 2-芳基-1-四氢萘酮是罗宾逊合成具有抗肿瘤活性的苯并[c]菲啶生物碱的关键中间体。在报告的碱性条件下处理模型酮酰胺（3a），可得到γ-酮-α，β-不饱和酸（9）和降解产物。用硼氢化钠还原 2，4-双芳基-4-氧代丁酰胺（3），可得到 2，4-双芳基-4-羟基丁酰胺（16），很容易将其氢解，得到 2，4-双芳基丁酰胺（15）。然而，令人遗憾的是，这种转化也倾向于得到一种 γ-内酰胺衍生物（17）。我们成功地将 2，4-双芳基-4-氧代丁酰胺 (3) 直接氢解为 2，4-双芳基丁酰胺 (15)，后者可以顺利地水解为相应的酸 (5)。此外，还研究了 Cheng 等人报告的 2，4-二芳基-4-氧代丁腈（2）直接水解为 2，4-二芳基-4-氧代丁酸（6）的情况。制备了十种 2-芳基-1-四氢萘酮（4），作为合成各种苯并[c]菲啶生物碱的起始原料。
