  Novel Ring Contraction of 3-Hydroxy-2,4(1H,3H)-quinolinediones in Aqueous Alkali. The First Convenient Route to 2-Hydroxyindoxyls

  摘要：

  Ring contraction of 3-hydroxy-2,4(1H,3H)-quinolinediones (1) in aqueous potassium hydroxide resulted in the formation of 2-hydroxyindoxyls and/or dioxindoles. The choice of N-substituent and the reaction conditions govern the chemoselectivity of the reaction. N-Phenyl-substituted derivatives 1 give 2-hydroxyindoxyls, while N-alkyl- and N-benzyl-substituted derivatives afford the corresponding dioxindols. On the basis of byproduct analysis, as well as independent experiments, the most plausible reaction mechanism is proposed.

  3-(Fluoroacyloxy)quinoline-2,4(1H,3H)-diones react with triethyl phosphite to afford either the product of the Perkow reaction or the corresponding 4-ethoxyquinolin-2(1H)-one. In both reactions, the fluorocarboxylate anion acts as the leaving group. For the corresponding 3-(fluoroiodoacetoxy) derivative this observation precludes the application of the intramolecular Wittig–Horner synthesis to modify

  3-（氟酰氧基）喹啉-2,4（1 H，3 H）-二酮与亚磷酸三乙酯反应，得到Perkow反应的产物或相应的4-乙氧基喹啉-2（1 H）-一。在两个反应中，氟代羧酸根阴离子都作为离去基团。对于相应的3-（氟碘乙酰氧基）衍生物，该观察结果排除了分子内Wittig-Horner合成方法的应用，该方法是通过氟化丁-2-烯内酯部分的环化来修饰喹啉-2,4（1 H，3 H）-二酮。

  3-Chloroquinoline-2,4-diones react with cyanide ions in dimethyl formamide to give 3-cyanoquinoline-2,4-diones in small yields due to the strong hindrance of the substituent at the C-3 atom. Good yields can be achieved if the substituent at this position is the methyl group. In the methanol solution, the reaction proceeds by an addition mechanism to form 2-oxo-1a,2,3,7b-tetrahydrooxireno[2,3-c]qui

  3-氯喹啉-2,4-二酮与氰化物离子在二甲基甲酰胺中反应生成3-氰基喹啉-2,4-二酮，由于C-3原子上取代基的强烈位阻，产率较低。如果该位置的取代基是甲基，则可以获得良好的产率。在甲醇溶液中，反应通过加成机制进行，形成2-氧代-1a,2,3,7b-四氢氧并[2,3 -c ]喹啉-7b-甲腈，其中4-羟基-3-甲氧基-随后通过用甲醇打开环氧化物环形成2-氧代-1,2,3,4-四氢喹啉-4-甲腈。这些反应的一些次要产物也已被分离出来。测量所制备的化合物的1 H、 13 C 和15 N NMR 谱，并使用适当的二维谱分配所有共振。
