Solvent Effects: Syntheses of 3,3-Difluorooxindoles and 3-Fluorooxindoles from Hydrazonoindolin-2-one by Selectfluor
摘要:
Efficient syntheses of 3,3-difluorooxindoles and 3-fluorooxindoles via fluorination of hydrazonoindolin-2-one with Selectfluor are reported. Under different solvent conditions, this method produced 3,3-difluorooxindoles and 3-fluorooxindoles selectively. The broad substrate scope and mild reaction conditions make this transformation a valuable method in drug discovery and development.

An original and efficient synthesis of 3,3-difluoro-2-oxindole derivatives has been developed via copper/B2pin2-catalyzed difluoroacetylation of aniline via C–H activation followed by intramolecular amidation.
the main pharmacophore group of imatinib. The 1,2,3-triazole core was used as a spacer in the derivatives through a click chemistry reaction and gave good yields. All the analogs were tested against A549 and K562cells, lung cancer and chronic myeloid leukemia (CML) cell lines, respectively. In A549 cells, the 3,3-difluorinated compound (3a), the 5-chloro-3,3-difluorinated compound (3c) and the 5-bromo-3
