  Synthesis of azafluorenones and related compounds using deprotocupration–aroylation followed by intramolecular direct arylation

  摘要：

  The efficiency of the deprotocupration-aroylation of 2-chloropyridine using lithiocuprates prepared from CuX (X=Cl, Br) and LiTMP (TMP=2,2,6,6-tetramethylpiperidido, 2 equiv) was investigated. CuCl was identified as a more suitable copper source than CuBr for this purpose. Different diaryl ketones bearing a halogen at the 2 position of one of the aryl groups were synthesized in this way from azines and thiophenes. These were then involved in palladium-catalyzed ring closure: substrates underwent expected CH-activation-type arylation to afford fluorenone-type compounds, and were also subjected to cyclization reactions leading to xanthones, notably in the presence of oxygen-containing substituents or reagents.

  使用氨基基锂铜酸盐对芳香族化合物进行去质子化金属化

  摘要：

  以2,4-二甲氧基嘧啶和2-甲氧基吡啶为底物，以苯甲酰氯为亲电子试剂，对基于氨基的铜酸锂对芳香族化合物的去质子化进行了优化。[（tmp）2 CuLi]（+2 LiCl）（tmp = 2,2,6,6-四甲基哌啶子基）被确定为最佳试剂，其应用范围已扩展到苯甲醚，1,4-二甲氧基苯，其他取代的吡啶，呋喃，噻吩及其衍生物和N -Boc-吲哚（Boc =叔-丁氧羰基）。在试图拦截所生成的芳基铜酸酯的亲电试剂中，芳酰氯，碘甲烷和二苯基二硫化物有效地反应了。另外，鉴定出不同的氧化剂以提供对称的联芳基。最后，优化了钯催化与芳基卤化物的偶联，并以中等收率合成了不同的芳基衍生物。

  employed to attempt the interception of the generated aryl cuprates, aroyl chlorides, iodomethane, and diphenyl disulfide efficiently reacted. In addition, different oxidative agents were identified to afford symmetrical biaryls. Finally, palladium‐catalyzed coupling with aryl halides was optimized and allowed the synthesis of different aryl derivatives in medium to good yields.

  The synthesis of triaryl methanols was investigated by reacting different 4-metalated 2-substituted pyrimidines with diaryl ketones, the latter being generated by deprotocupration-aroylation of azine and diazine substrates. Cyclization of the triaryl methanols thus obtained afforded pyrido[3,2:4,5]pyrrolo[1,2-c]pyrimidines, which were evaluated for kinase inhibition and antiproliferative activities in melanoma cells.
