The directarylation of substitutedpyridines with several arylboronicacids has been developed. This transformation could proceed readily at ambient temperature using inexpensive reagents: iron(II) oxalate as a catalyst, potassium persulfate as a co‐oxidant, which can afford the arylated products in mild to good yields. The mechanism is presumed to proceed through a nucleophilic radical addition to

Clostridioidesdifficile is a leading health threat. This pathogen initiates intestinal infections during gut microbiota dysbiosis caused by oral administration of antibiotics. C. difficile is difficult to eradicate due to its ability to form spores, which are not susceptible to antibiotics. To address the urgent need for treating recurrent C. difficileinfection, antibiotics that selectively target

The invention discloses compounds of Formula (I). The compounds of formula (I) are TRPA1 antagonists and are useful as active ingredients of pharmaceutical compositions for the treatment of pain and other conditions ameliorated by the inhibition of TRPA1 receptors.
In the past years, the activations of aromaticnitriles for radical arylations under photoirradiation have been developed. We here report the first example of radical arylations using aromaticnitriles without the assistance of photoirradiation. Importantly, with this method, the direct arylation of C(sp3)–H in benzyl amines provided a practical method for the synthesis of diarylmethylamines without
