A one-pot transition metal-free methodology for constructing pharmacologically active dibenzodiazepine derivatives was developed. Fluoro-, bromo- and nitro-substituted aryl aldehydes were applied to this reaction efficiently. A one-pot transition metal-free methodology for constructing pharmacologically active dibenzodiazepine derivatives was developed.
