Facile synthesis of quinoxaline annulated perfluoroalkylated benzoazepine derivatives†
Abstract
Novel perfluoroalkylated benzoazepinoquinoxaline derivatives were synthesized by consecutive intermolecular Michael addition and intramolecular cyclization from 3-(2-aminophenyl)quinoxalin-2(1H)-ones and methyl perfluoroalk-2-ynoates in good yields. This efficient and mild protocol might afford a new pathway for novel drug development.
