Anticancer potential of 3-hydroxypyridine-2-carboxaldehyde N(4)-methyl and pyrrolidinylthiosemicarbazones and their Zn(II) complexes in different cancers via targeting MAPK superfamily signaling pathway Four dinucleating bis(thiosemicarbazone) ligands and their zinc complexes have been synthesized and ...
The first iridium-catalyzed intermolecular asymmetric allylic amination reaction with 2-hydroxypyridines has been developed, thus providing a highly efficient synthesis of enantioenriched N-substituted 2-pyridone derivatives from readily available starting materials. This protocol features a good tolerance of ...
This protocol features a good tolerance of functional groups in both the allylic carbonates and 2-hydroxypyridines, thereby delivering multifunctionalized heterocyclic products with up to 98 % yield and 99 % ee.doi:10.1002/ange.201409976Xiao...
