- Quinoxalines, benzodiazepines and benzodiazocines fused to pyrrole and isoindole via N-acyliminium ion aromatic cyclization
-
Quinoxaline (6a), [1,4]benzodiazepines (6b,c) and [2,5]-benzodiazocine (6d) were synthesized from hydroxylactams (3a-d) or (4a-d) via an N- acyliminium ion-pyrrole cyclization reaction. 3 and 4 were prepared in two steps from ready available substituted anilines (1a,b) or benzylamines (1c,d).
