Certain imidazopyridines (I) and pharmaceutical compositions thereof are provided herein. Methods of treating patients suffering from certain diseases and disorders responsive to the inhibition of Syk activity, which comprises administering to such patients an amount of at least one chemical entity effective to reduce signs or symptoms of the disease or disorder are provided. Also provided are methods for determining the presence or absence of Syk kinase in a sample.
metal–catalyzed asymmetric allylicsubstitution reactions are well known for installing stereocenters adjacent to branched or E-linear olefins. However, analogous reactions for the synthesis of optically active Z-olefin products are rare. Here we report iridium-catalyzed asymmetric allylicsubstitution reactions that retain Z-olefin geometries while establishing an adjacent quaternary stereocenter. The formation

hetero‐Pictet‐Spengler reaction has been developed, enabling divergent approaches to plenty of structurally diverse polyheterocyclic spirooxindoles and 3,3‐bistryptophol oxindoles from readily available isatins and substituted aromatic heterocyclic derivatives in up to 98% yield. Mechanistic investigation reveals that the perchloric acid generated upon on hydrolysis of Fe(ClO4)3 ⋅ 6H2O by residual water was the real
