Synthesis

The synthesis of 2-Nitrodiphenylamine is as follows:The mixture of phenylboronic acid (1 mmol), aromatic amine (1.2 mmol) and 0.12 g (2 mmol) of KF in DMSO (4 mL) were added to Cu-IS-AMBA-MNPs (0.06 g, 0.025 mmol) at 130 °C under nitrogen atmosphere for 2 h with vigorous stirring. Then, after completion of the reaction, the catalyst was separated by an external magnet and washed with dry CH2Cl2?three times and checked for its reusability. The solvent of the reaction mixture was evaporated by a rotary evaporator and then ethyl acetate and water were added to the residue. The organic layer was dried over anhydrous MgSO4. The solvent was evaporated under reduced pressure and the crude product was purified by column chromatography using ethyl acetate/n-hexane.

The synthesis of the naturally occurring toxin pyocyanin has been realized in a short 4 step sequence. The key photochemical reaction and isolation of the final product have been facilitated by the use of flow chemistry techniques and immobilised reagents. Using these procedures gram quantities of pyocyanin were easily prepared in high yield and purity.

Design, synthesis, and structure-activity relationships of novel imidazo[4,5-c]pyridine derivatives as potent non-nucleoside inhibitors of hepatitis C virus NS5B

The hepatitis C virus (HCV) NS5B polymerase is an attractive target for the development of novel and selective inhibitors of HCV replication. In this paper, the design, synthesis, and preliminary SAR studies of novel inhibitors of HCV NS5B polymerase based on the structure of tegobuvir have been described. The efforts to optimize the antiviral potency and reduce the treatment side effects with respect to genotype 1b resulted in the discovery of compound 3, which exhibited an EC50 of 1.163 nM and a CC50 >200 nM in a cell-based HCV replicon system assay. Additionally, testing for inhibition of the hERG channel showed a marked improvement over tegobuvir and the pharmacokinetic properties of compound 3 indicated that it was worthy of further investigation as a non-nucleoside inhibitor of HCV NS5B polymerase.

A terphenyl phosphine as a highly efficient ligand for palladium-catalysed amination of aryl halides with 1° anilines

A terphenyl phosphine ligand (2,6-bis(2,4,6-triisopropylphenyl)phenyl-dicyclohexylphosphine, TXPhos) and its supported palladium complex [(TXPhos)(allyl)PdCl] have been developed and the catalyst system is highly efficient in amination of aryl halides with 1° anilines, especially effective for densely functionalized substrates including both partners possessing ortho-ester, acetyl, nitrile and nitro groups. With the TXPhos-supported catalyst system, many partner combinations have been unprecedentedly realized and the base scope has been even extended to KOAc, which is even the best choice in the amination of 2-nitrochlorobenzene.
