difluoromethylation of heteroaromatic compounds using off-the-shelf difluoroacetic acid as the difluoromethylating reagent has been developed. Mono-difluoromethylation versus bis-difluoromethylation is controlled as the result of the reaction temperature. The reactions described here enable access to the late-stage C−H mono- and bis-difluoromethylation for preparation of tool compounds for chemical biology and

Herein, we demonstrate that 2-difluoromethylpyridine is a bioisosteric replacement of pyridine-N-oxide. Using the quorum sensing inhibitor 4NPO as a model compound, a library of 2-difluoromethylpyridine derivatives was designed, synthesized, and evaluated toward quorum sensing activity, biofilm formation, anti-violacein activity, and protease activity. As a result, compounds 1 (IC50 of 35 ± 1.12 μM)
A reagent for carrying out a difluoromethylation reaction of unsaturated compounds and ring-nitrogen-containing aromatic compounds, a zinc difluoro-methanesulfinate, as well as a method for making the reagent and a method for its use are disclosed.
