Stereoselective process for producing 5-aryl-8,9-dihydro-7H-1,3-dioxolo¬4,5-h¾-2,3-benzodiazepine derivatives and the intermediate 5-aroyl-6-(2-substituted alkyl)-1,3-benzodioxole hydrazone derivatives therefor

摘要

A process for stereoselectively forming N-substituted dihydro-2,3 benzodiazepines of formula (I) which are useful as AMPA receptor antagonists, and novel intermediates useful in the process. CHEM
