α-Chymotrypsin from the bovine pancreas has been shown for the first time to display catalytic nonnatural catalytic ability toward the C (sp3)–H functionalization reaction of 2-methylquinoline and aromatic aldehydes in water. α-Chymotrypsin exhibited favorable catalytic activity with good adaptability to different substrates. The activity of the enzyme could be improved by adjusting the solvent, temperature, molar ratio of substrates, and protein loading. The products were obtained in moderate to excellent yields (51%-93%) in 24 samples. This process afforded a potential biocatalytic approach as an alternative to chemical synthesis for azaarene derivatives.

A highly efficient method is described for the sp3 C-H bond functionalization of methyl aza-arenes in the presence of water under microwave irradiation and subsequent addition to aromatic aldehydes. This transformation represents an efficient way to synthesize 2-alkyl aza-arene derivatives from simple starting materials.

supporting information, p. 8605 - 8608 (2013/01/15)
A practical Bronsted acid promoted benzylic C-H functionalization of 2-methylazaarenes and nucleophilic addition to aldehydes was developed in good to excellent yields. A six-membered hydrogen-bonding transition state is proposed to be crucial for the reaction. Ready availability of the two starting materials, the use of acetic acid as the catalyst and the facile reaction conditions will guarantee this synthetic method attractive to the synthesis of bioactive pyridine and quinoline derivatives.
