The present invention relates to dihydro-2,3-benzodiazepine compounds of high enantiomeric purity according to the general formula (I), which contain an asymmetric centre at the position 4 of the dihydro-2,3-benzodiazepine compound, and the preparation thereof and the used intermediates as well. These compounds have anti-convulsiveA muscle relaxant and neuroprotective effect due their non-competitive AMPA antagonistic properties.
