  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.

  Bedaquiline的结构简化：3（4-（N，N-二甲基氨基甲基）苯基）喹啉衍生的抗结核先导化合物的发现

  摘要：

  Bedaquiline（BDQ）是一种新型的高效抗结核药物，已于2013年获得美国FDA批准。由于立体结构的复杂性，化学合成和化合物优化非常困难且昂贵。这项研究描述了苯达喹啉的结构简化，同时保留了抗结核活性。该化合物的结构被分为多个片段，并以各种组合重新组装，同时用非手性键取代了两个手性碳原子。设计了四个系列的类似物。这些候选药物对敏感和耐多药（MDR）结核分枝杆菌均保持其有效的抗结核活性，浓度为每微克每毫升。株。六出前的被发现有9 MIC-排名候选抑制分枝杆菌ATP合成与IC活性50 20和40μ之间的值米，一个有IC 50 > 66μ米，和两个显示无抑制，尽管它们抗结核活性。这些结果为开发化学上不太复杂，成本更低的苯达喹啉衍生物提供了基础，并描述了对非ATP合酶相关靶标具有抗结核活性的两种衍生物的鉴定。

  A series of chloro‐ and bromopyridines have been deprotometalated by using a range of 2,2,6,6‐tetramethylpiperidino‐based mixed lithium–metal combinations. Whereas lithium–zinc and lithium–cadmium bases afforded different mono‐ and diiodides after subsequent interception with iodine, complete regioselectivities were observed with the corresponding lithium–copper combination, as demonstrated by subsequent

  通过使用一系列基于2,2,6,6-四甲基哌啶子基的混合锂金属组合，已将一系列氯吡啶和溴吡啶进行了脱金属处理。锂锌和锂镉碱在随后被碘截留后提供不同的一碘化物和二碘化物，而相应的锂铜组合则观察到了完全的区域选择性，随后通过苯甲酰氯的捕集证明了这一点。已经根据底物的CH酸来讨论了所获得的选择性，所述底物的CH酸是在气相中以及通过使用DFTB3LYP方法作为在THF中的溶液而确定的。

  An efficient method for the synthesis of (hetero)arene-fused 2,2-difluoro-2,3-dihydrothiophene derivatives using readily available sodium chlorodifluoroacetate (ClCF2CO2Na) has been developed. This transformation is achieved through a combination of a thiolate with difluorocarbene, followed by intramolecular nucleophilic addition to a ketone, cyano, or ester functional group.

  Crystals of a lithiocuprate prepared from copper(I) chloride and lithium 2,2,6,6-tetramethylpiperidide (2 equiv) were isolated and analyzed by X-ray diffraction as (TMP)(2)Cu(Cl)Li-2 center dot THF. The observation of this species is consistent with its having a role in deprotocupration-aroylation. Phenyl pyridyl ketones, phenyl quinolyl ketones, and phenyl thienyl ketones were prepared in tetrahydrofuran using the lithiocuprate and aroyl chorides as electrophiles. Diaryl ketones bearing a chloro group at the 2 position (of a pyridyl or phenyl group) thus synthesized were next converted through palladium-catalyzed ring closure to polycycles of the 5H-indeno[1,2-b]pyridin-5-one, 11H-indeno[1,2-b]quinolin-11-one, 9H-indeno[2,1-c]pyridin-9-one, and 8H-indeno[2,1-b]thiophen-8-one families.
