- Abstract
- Electrochemical C-H oxidation/conjugate addition/cyclization sequences of 2-alkyl phenols with malononitrile are described. This transformation is an environmentally friendly approach by successfully avoiding the use of stoichiometric amounts of external redox reagents. Various 2-amino-4H-chromene derivatives are afforded in moderate to high yields through a one-pot process from 2-benzyl or 2-cinnamyl phenol derivatives under mild reaction conditions.
