The development of green and efficient methods for hydrogenation of nitroarenes is still highly demanding in organic synthesis. Herein, we report an industrial Cunninghamia lanceolata carbon supported FeO(OH) nanoparticles process for the synthesis of aryl amines with good yields via hydrogenation of nitroarenes. Nine key anti-cancer drug intermediates were successfully achieved with protocol. And Osimertinib intermediate 4m can be smoothly synthesized at a 2.67 kg-scale with >99.5% HPLC purity. This protocol features cheap carbon source, highly catalytic activity, simple operation, kilogram-scalable and recyclable catalysts (eight times without observable losing activity).

Page/Page column 0185, (2020/03/28)
A chemoselective and reactive Mn(CF3-PDP) catalyst system that enables for the first time the strategic advantages of late-stage aliphatic C—H hydroxylation to be leveraged in aromatic compounds. This discovery will benefit small molecule therapeutics by enabling the rapid diversification of aromatic drugs and natural products and identification of their metabolites.
