naphthoquinone imidazolin-2-ylidene-palladium(0) complexes were found to be highlyactive one-component catalysts for the amination of aryl halides. With these very robust catalysts, the expensive bases Cs 2 CO 3 or NaOt-Bu traditionally used can be replaced by KOH. A convenient reaction protocol has been developed for the coupling of a wide range of arylchlorides with primary or secondary amines.

A facile nickel-catalyzed method to achieve the amination of synthetically useful arylsulfamates and carbamates is reported. Contrary to most Ni-catalyzed amination reactions, this user-friendly approach relies on an air-stable Ni(II) precatalyst, which, when employed with a mild reducing agent, efficiently delivers aminated products in good to excellent yields. The scope of the method is broad with
报道了一种简便的镍催化方法来实现合成有用的氨基磺酸芳基酯和氨基甲酸酯的胺化。与大多数 Ni 催化的胺化反应相反,这种用户友好的方法依赖于空气稳定的 Ni(II) 预催化剂,当它与温和的还原剂一起使用时,可以有效地以良好到优异的产率提供胺化产物。该方法的范围就两个偶联伙伴而言都是广泛的,并且包括杂环底物。

The nickel-catalyzedamination of aryl O-sulfamates and chlorides using the green solvent 2-methyl-THF is reported. This methodology employs the commercially available and air-stable precatalyst NiCl2(DME), is broad in scope, and provides access to aryl amines in synthetically useful yields. The utility of this methodology is underscored by examples of gram-scale couplings conducted with catalyst loadings

Areneactivation via transition-metal (TM) η6-coordination has merged as a powerful method to diversify the aromatic C–F bond, which is relatively less reactive due to its high bond energy. However, this strategy in general requires to use largely excess arenes or TM η6-complexes as the substrates. Herein, we highlight our recent work on the catalytic SNAr amination of electron-rich and electron-neutral

Thienopyridinone compounds of Formula (I) and pharmaceutically acceptable salts thereof are described. In these compounds, one of X1; X2, and X3 is S and the other two are each independently CR, wherein R and all other variables are as defined herein. The compounds are shown to inhibit HPK1 kinase activity and to have in vivo antitumor activity. The compounds can be effectively combined with pharmaceutically acceptable carriers and also with other immunomodulatory approaches, such as checkpoint inhibition or inhibitors of tryptophan oxidation. Formula (I).
