Abstract
International audienceQuinoxaline (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)Keywords
