ChemInform Abstract: Dynamic Kinetic Resolution Approach for the Asymmetric Synthesis of Tetrahydrobenzodiazepines Using Transfer Hydrogenation by Chiral Phosphoric Acid.

Dihydrobenzodiazepines or benzodiazepines bearing aryl substituents at the 2- and 4-position of the heterocyclic part are transformed to the chiral title compounds in the presence of BNPA using different amounts of the hydrogen transfer reagent BTA. [ABSTRACT FROM AUTHOR]
