Synthesis of Bridged Benzodiazepines by Reaction of Amines and Hydrazine Derivatives with 4,6-Dibromomethyl-5,2,8-etanylylidene-5H-1,9-benzodiazacycloundecine

Bromination of 4,6-dimethyl-5,2,8-ethanylylidene-5H-1,9-benzodiazacycloundecine with N-bromosuccinimide gives a number of brominated products.Reaction of the dibromo and tribromo derivatives with amines and hydrazine derivatives are described.Amines give dihydro derivatives of bridged 14? annulenes, while the hydrazine derivatives give tetrahydro analogues of bridged 14? annulenes.Oxidation studies with the dihydro- and tetrahydro-annulenes are reported.
