Cu–benzotriazole-catalyzed electrophilic cyclization of N-arylimines: a methodical tandem approach to O-protected-4hydroxyquinazolines-?
RSC Advances Pub Date: 2014-08-05 DOI: 10.1039/C4RA07377K
Abstract
A remarkably efficient approach to O-protected-4-hydroxyquinazolines has been developed via the copper–benzotriazole (Cu–BtH)-catalyzed intramolecular electrophilic cyclization of N-arylimines, achieved through the reaction of 2-aminobenzonitriles and various aldehydes.
