A C-H functionalization strategy for the expedient access to photoreactive chemical probes of commonly found heterocyclic fragments or drug molecules of pharmaceutical relevance is described. A series of aryl glyoxylic acid reagents featuring pendant alkyne or azide clickable handles have been developed for application in the radical-mediated appendage of benzoyl fragments onto simple heteroaromatic
Herein is described an efficient and chemoselective method for the synthesis of diversely substituted secondary amines in yields up to 98 %. Direct mono-N-alkylation of primary benzylamines and anilines with a wide range of alkyl halides is promoted by a cesium base in the absence of any additive or catalyst. The basicity and solubility of cesium carbonate in anhydrous N,N-dimethylformamide not only

By revealing the robust photooxidant properties of phenalenyl-based organic Lewis acid, we have introduced this moiety as an effective organophotocatalyst for the oxidative azolation of unactivated and feedstock arenes. In addition to its tolerance for various functional groups and scalability, this photocatalyst was shown to be promising for the defluorinative azolation of fluoroarenes.
