  well-defined copper(II)-7-azaindole-N-oxide-based catalyst [Cu2II(7-AINO)4] (abbreviated as Cu(II)-7-AINO) has been demonstrated as an efficient catalyst for various Ullmann-type coupling reactions. This easily prepared and cost-effective catalyst facilitates the arylation and heteroarylation of diverse N-, S-, and O-nucleophiles, including azoles, aminoazoles, (hetero)arylthiols, and phenols. Notably

  一种空气稳定、稳健且定义明确的铜（II）-7-氮杂吲哚-N-氧化物基催化剂 [Cu2II（7-AINO）4]（缩写为 Cu（II）-7-AINO）已被证明是各种 Ullmann 型偶联反应的有效催化剂。这种易于制备且经济高效的催化剂有助于各种亲核试剂（包括唑类、氨基唑类、（杂）芳基硫醇和酚类）的芳基化和杂芳基化。值得注意的是，它们还表现出与各种官能团的显著相容性。此外，在这两种情况下，该催化剂对氨基唑类化合物的 –NH 位点和氨基硫酚类化合物的 –SH 位点均表现出显著的选择性，优于 –NH2 位点，增强了其多功能性。利用催化剂的化学选择性和区域选择性，我们已经成功地证明了我们的方法在合成各种药物分子中的适用性。具体来说，使用我们的方案成功合成了 Epirizole 类似物、Nilotinib 和 Vortioxetine。

  Rational design of a novel template of naphthyridinones rapidly led to PDE4 inhibitors with subnanomolar enzymatic potencies. X-ray crystallography confirmed the binding mode of this novel template. We achieved compounds with double-digit picomolar enzymatic potencies through further structure-based design by targeting both the PDE4 enzyme metal binding pocket and occupying the solvent-filled pocket. A strategy for lung retention and long duration of action based on low aqueous solubility was followed. In vivo efficacies were measured in a rat lung neutrophilia model by suspension microspray and dry powder administration. Suspension microspray of potent compounds showed in vivo efficacy with a clear dose-response. Despite sustained lung levels, dry powder administration performed much less well and without proper dose-response, highlighting clear differences between the two formulations. This indicates a deficiency in the low aqueous solubility strategy for long duration lung efficacy.

  AbstractThe N1‐selective arylation of 3‐aminoindazoles using copper catalysis is herein reported. The reaction uses readily accessible aryl bromides as coupling partners, including those from heterocycles, and allows easy access to a broad variety of substituted 3‐aminoindazoles. The methodology was also examined on other aminoazoles of interest for the pharmaceutical industry.

  Copper(II)-catalyzed boronic acid promoted C-N bond cross-coupling reactions have been successfully developed for sequential N-arylation of C-amino-NH-azoles. These general protocols are compatible with a variety of aryl/hetero-aryl boronic acids and provided rapid access to a diverse array of diarylaminoazole derivatives in a two-step sequence or in one-pot.
