α-Amino azines are widely found in pharmaceuticals and ligands. Herein, we report a practical method for accessing this class of compounds via photocatalyzed hydroarylation of azine-substituted enamides with the in situ-generated aryl thianthrenium salts as the radical precursor. This reaction features a broad substrate scope, good functional group tolerance, and mild conditions and is suitable for the late-stage installation of α-amino azines in complex structures.

In this study, we developed a catalytic system for the C-alkylation of a methyl group on N-heteroaromatic compounds, including pyridine, pyrimidine, pyrazine, quinoline, quinoxaline, and isoquinoline, using alcohols based on a hydrogen-borrowing process with [Cp*IrCl2]2 (Cp*: η5-pentamethylcyclopentadienyl) combined with potassium t-butoxide and 18-crown-6-ether as the catalyst precursor.

(Chemical Equation Presented) A novel catalytic C-C coupling reaction in which N-heteroaromatic-substituted methyl groups are efficiently alkylated using primary alcohols is introduced. The synthesis protocol is based on iridium catalysts and most likely relies on the borrowing hydrogen or hydrogen autotransfer mechanism. A variety of substrate combinations can readily be employed in this reaction, including pyrimidines, pyrazines, pyridazines, and even fairly activated 2- and 4-picolines. Copyright
