  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。

  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.
