Organocatalyzed One-Pot Synthesis of Substituted 1,5-Benzodiazepine and Benzimidazole Derivatives

Abstract

An efficient synthesis of some heterocycles is described by condensation between o-phenylenediamine and 1,3-dicarbonyl compounds catalyzed by L-proline. The reaction is carried out either at room temperature or reflux depending on the substrates.
