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

A highly efficient method is described for the sp(3) 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. (C) 2013 Elsevier Ltd. All rights reserved.
