N-alkyl isoindolo[2,1-b][2,4]benzodiazepines 15c were synthesized via an intramolecular N-acyliminium ion-amide reaction, N-aryl derivatives 8c were obtained from an intramolecular acylation of amino acids 6c in acetic anhydride. A generalization of these methodologies is given in the synthesis of the thiophenic analogues 15d and 8d.
