  Design and synthesis of 2-amino-isoxazolopyridines as Polo-like kinase inhibitors

  摘要：

  A series of 2-amino-isoxazolopyridines was designed and synthesized as Polo-like kinase (Plk) inhibitors. Key SAR and crystallographic data are discussed. More advanced analogues inhibit Plk1 with good enzymatic activity and modest cell-based activity. Differential selectivity among the three Plk isoforms is observed.

  使用酰胺基双金属物种和区域选择性计算的CH酸度关系对氯和溴吡啶进行去质子化金属化

  摘要：

  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。

• Synthesis of substituted azafluorenones from dihalogeno diaryl ketones by palladium-catalyzed auto-tandem processes

  日期：——

  Substituted azafluorenones were synthesized from different dihalogeno diaryl ketones under palladium catalysis by combining either Suzuki or Heck coupling with direct cyclizing arylation. Conditions were identified to allow both auto-tandem processes to proceed successfully from 3-(bromobenzoyl)- or 3-benzoyl-4-bromo-2-chloropyridines, as well as 4-benzoyl-2,3- and 4-benzoyl-2,5-dichloropyridines.

  Substituted azafluorenones were synthesized from dihalogeno diaryl ketones under palladium catalysis by combining, in auto -tandem processes, Suzuki coupling and intramolecular arylation reactions. Different dihalogenated diaryl ketones, prepared by sequential deprotocupration-aroylation, were identified as suitable substrates to this purpose. Conditions were identified to allow successful syntheses of several 6-/7-arylated 4-azafluorenones, 1 -substituted 4-azafluorenones, 2-phenyl-3-azafluorenone, and 4-phenyl-3-azafluorenone from 3-(bromobenzoyl)-2-chloropyridines, 3-benzoyl-4-bromo-2-chloropyridines, 4-benzoyl-2,5-dichloropyridine, and 4-benzoyl-2,3-dichloropyridine, respectively. Some of the synthesized compounds exhibit interesting biological properties. (C) 2015 Elsevier Ltd. All rights reserved.

  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
