Functionalization of Benzylic sp3 C-H of 2-Methylazaarenes in Deep Eutectic Solvent
摘要:
The catalyst-free addition of 2-methylazaarene benzylic sp(3) C-H to electron-deficient olefins in deep eutectic solvents is reported. Moderate to good yields were obtained in 2 h at 80 degrees C in deep eutectic solvents. The method was operationally easy and involved mild reaction conditions. This expands the application of deep eutectic solvent in sp(3) C-H functionalization reaction.

Benzylic sp3 C-H Functionalization Reaction of 2-Methylazaarenes Catalyzed by Pepsin
In this work, the addition of 2-methylazaarenes benzylic sp(3) C-H to electron-deficient olefins, catalyzed by pepsin from pig gastric mucosa was reported. A series of azaarene derivatives (1 mmol) were obtained in good yields at 60 degrees C for 60 similar to 72 h with 20 mg pepsin as catalyst. This is a facile method and the reaction conditions are mild, which expands the application of biocatalysis in sp(3) C-H functionalization of azaarenes.
