Annular dibromination of hydroxypyridines with NBS in acetonitrilefollowed by bromine-lithium exchange with RLi and subsequent trappingwith H2O or I2 afforded monobromo and bromoiododerivatives in a completely regioselective way. Iodination of bromohydroxypyridines with NIS is totally regioselective.

excellent regioselectivity. A one-pot synthesis of unsymmetrical 3,5-diaryl-2-pyridones starting from 3,5-dibromo-2-silyloxypyridine was conducted to demonstrate the practical convenience. Further functionalization onto the remaining bromine group, such as transition metal-catalyzed C−C and C−N bond-forming reactions and retro-Brook rearrangement for C−Si bond formation, was accomplished for synthesis of
Heteroaryl pyridone and aza-pyridone compounds are provided, including stereoisomers, tautomers, and pharmaceutically acceptable salts thereof, useful for inhibiting Btk kinase, and for treating immune disorders such as inflammation mediated by Btk kinase. Methods of using heteroaryl pyridone and aza-pyridone compounds for in vitro, in situ, and in vivo diagnosis, and treatment of such disorders in mammalian cells, or associated pathological conditions, are disclosed.
