Palladium-catalyzed amination proved to be a valuable strategy for the selective introduction of aromatic and heteroaromatic amines, including aminopyridines and aminodiazines, on dichloropyridines. The use of mild amination conditions resulted in maximum selectivity and excellent base sensitive functional group tolerance.
The present invention provides compounds, compositions thereof, and methods of using the same for the inhibition of CRBN, and the treatment of CRBN-mediated disorders.
本发明提供了化合物、其组合物以及使用这些化合物抑制CRBN和治疗CRBN介导的疾病的方法。

I and 3-aryl/alkylamino-2-aryl pyridines II, as important potentially bioactive compounds, were synthesized by applying orthogonalcross-couplingstrategies. Combinations of the Suzuki–Miyaura, Liebeskind–Srogl, and Buchwald–Hartwig protocols gave access to the title compounds in a straightforward and operationally simple manner. Full control over the regioselectivity at the 2- and 3-positions was achieved
