  Synthesis, Antibacterial and Antioxidant Properties of Pyrazolylpyridazines

  摘要：

  A number of 6-chloro-3-(pyrazol-1'-yl) pyridazines were prepared from 3,6-dichloropyridazine via either reaction with hydrazine followed by reaction with appropriate reagents to develop the pyrazole or through a nucleophilic reaction with a pyrazole. Some electrophilic reactions gave the corresponding 4'-substituted pyrazolylpyridazines. All the compounds were tested for their in vitro antibacterial as well as their antioxidant properties.

• Mild and Highly Selective Palladium-Catalyzed Monoarylation of Ammonia Enabled by the Use of Bulky Biarylphosphine Ligands and Palladacycle Precatalysts
  作者：Chi Wai Cheung、David S. Surry、Stephen L. Buchwald

  DOI：10.1021/ol401612c

  A method for the Pd-catalyzed arylation of ammonia with a wide range of aryl and heteroaryl halides, including challenging five-membered heterocyclic substrates, is described. Excellent selectivity for monoarylation of ammonia to primary arylamines was achieved under mild conditions or at rt by the use of bulky biarylphosphine ligands (L6, L7, and L4) as well as their corresponding aminobiphenyl palladacycle

This report addresses this challenge by leveraging tetramethylammonium fluoride alcohol adducts (Me4NF·ROH) as fluoride sources for SNAr fluorination.

  An improved protocol for the Pd-catalyzed C–O cross-coupling of secondary alcohols is described. The use of biaryl phosphine L2 as the ligand was key to achieving efficient cross-coupling of (hetero)aryl chlorides with only a 20% molar excess of the alcohol. Additionally, we observed an unusual reactivity difference between an electron-rich aryl bromide and the analogous aryl chloride, and deuterium-labeling
