Enamines (1a-r) prepared from cyclohexanones, cyclohexane-1,3-diones, or tetralones led to arylamines (2a-r) in one pot when treated with a stoichiometric amount of palladium salts [PdCl2-(MeCN)2] in acetonitrile in the presence of triethylamine at room temperature or at elevated temperature, in some cases for 5 min to 2 h. The initial electrophilicattack of palladium chloride on the beta-carbon of
The invention provides compounds that inhibit CK2 and/or Pim kinases and compositions containing such compounds. These tricyclic compounds and compositions containing them are useful for treating proliferative disorders such as cancer, as well as other kinase-associated conditions including inflammation, pain, pathogenic infections, and certain immunological disorders.
we report a new synthetic strategy for 2-(pyridin-2-yl)phenols and 2-(pyridin-2-yl)anilines catalyzed by a Pd/C–ethylene system. The starting materials, 2-(pyridin-2-yl)cyclohexan-1-ones, can be easily prepared by the reaction of substituted pyridine N-oxide and cyclohexanones. The most useful feature of this method is that both 2-(pyridin-2-yl)phenols and 2-(pyridin-2-yl)anilines are easily synthesized
