Synthesis of bridged 1,5-benzodiazepines by condensation of o-phenylenediamines with 4,6-dimethylbicyclo[3.3.1]nona-3,6-diene-2,8-dione
Abstract
o-Phenylenediamines react with 4,6-dimethylbicyclo[3.3.1]nona-3,6-diene-2,8-dione to give 1,5-benzodiazepines; physical and chemical properties of the bridged imines are described.
