The alkoxybenzylidene ligand of Hoveyda-Grubbs 1st and 2nd generation catalysts was modified with one or two perfluorohexyl groups by Ullmann reaction with the aim to improve both the fluorophilicity and activity of the catalyst. While bis(perfluorohexyla

Regioselective I/Zn-exchange reactions were performed on polyiodinated arenes or heterocycles within 20 minutes at 0-25 °C using the bimetallic combination pTol2Zn2LiOR [R = (CH2)2N(Me)(CH2)2NMe2] in toluene. The resulting diaryl- or diheteroarylzincs reacted well with allylic bromides and acyl chlorides to provide functionalized (hetero)- aryl iodides in good yields.

Protein arginine deiminases (PADs) hydrolyze the side chain of arginine to form citrulline. Aberrant PAD activity is associated with rheumatoid arthritis, multiple sclerosis, lupus, and certain cancers. These pathologies established the PADs as therapeutic targets and multiple PAD inhibitors are known. Herein, we describe the first highly potent PAD1-selective inhibitors (1 and 19). Detailed structure–activity relationships indicate that their potency and selectivity is due to the formation of a halogen bond with PAD1. Importantly, these inhibitors inhibit histone H3 citrullination in HEK293TPAD1 cells and mouse zygotes with excellent potency. Based on this scaffold, we also developed a PAD1-selective activity-based probe that shows remarkable cellular efficacy and proteome selectivity. Based on their potency and selectivity we expect that 1 and 19 will be widely used chemical tools to understand PAD1 biology.
