  摘要：

  AbstractProduct selectivity control for the synthesis of imidoylindoles and 4‐alkylidenedihydroquinazolines from N‐imidoyl‐o‐alkynylanilines via silver triflate‐catalyzed cycloisomerization or tetrabutylammonium fluoride‐promoted cyclization is described. The product selectivity depends mainly on the catalyst/promoter used, and on the substituents on the alkyne and amidine functions of the substrates.magnified image

• Biradicals from Thermolysis of <i>N</i>-[2-(1-Alkynyl)phenyl]-<i>N</i>‘-phenylcarbodiimides and Their Subsequent Transformations to 6<i>H</i>-Indolo[2,3-<i>b</i>]quinolines

  Thermolysis of the carbodiimide 9a in gamma-terpinene at 138 degrees C produced 2-(phenylamino)quinoline (11a, 49%) and the parent 6H-indolo[2,3-b]quinoline (14a, 16%). Apparently, 11a was produced via the biradical 10a followed by hydrogen-atom abstraction from gamma-terpinene. A two-step biradical pathway through 12a or a one-step intramolecular Diels-Alder reaction could furnish 13a, which then

  碳二亚胺9a在138℃下在γ-萜品烯中的热解产生2-（苯氨基）喹啉（11a，49％）和母体6H-吲哚并[2,3-b]喹啉（14a，16％）。显然，通过双自由基10a生成11a，然后从γ-萜品烯中提取氢原子。通过12a的两步双自由基途径或一个分子内Diels-Alder反应一步可提供13a，然后将其进行互变异构化得到14a。对于在乙炔基末端具有三甲基甲硅烷基取代基的碳二亚胺9b，在138℃下在回流的对二甲苯中热解仅产生6H-吲哚并[2，3-b]喹啉14b（86％）。在回流的乙醇中用6 N NaOH处理14b，然后以92％的收率得到14a。类似地，通过碳二亚胺9c-f的热解获得6H-吲哚并[2,3-b]喹啉14c-f。通过使用4-甲氧基苯基异氰酸酯与亚氨基膦酸酯2d和2f之间的氮杂-维蒂希反应来产生相应的碳二亚胺，然后进行热分解，得到在C上具有甲氧基取代基的6H-吲哚并[2，3-b]喹啉16d和16f。

• C=C-conjugated carbodiimides as 2-aza dienes in intramolecular [4+2] cycloadditions. One-pot preparation of quinoline, .alpha.-carboline, and quinindoline derivatives

  Iminophosphoranes 2 derived from o-aminostyrenes react with aryl isocyanates to give the corresponding carbodiimides 13 which by thermal treatment at 160-degrees-C undergo 6-pi-electrocyclization to give quinoline derivatives 14. However, the reaction with styryl isocyanates leads to alpha-carbolines 19 through the intermediate carbodiimides 15 which undergo a tandem intramolecular hetero-Diels-Alder cycloaddition/aromatization process to give 19. Similarly, related alpha-carbolines 20-22 can be obtained from the reaction of iminophosphoranes derived from ortho-substituted anilines containing an unsaturated side chain with styryl isocyanates. Iminophosphorane 6a, derived from o-butadienylaniline, and related 10 and 12 react with aryl isocyanates under the same reaction conditions to give quinindoline derivatives 25-27, respectively. Finally, iminophosphoranes 2 and 6 by reaction with ketenes lead directly to quinolines 32 and benzo[b]carbazoles 33, respectively.
