The one pot synthesis of perimidine and 1,5-benzodiazepine derivatives via condensation of aryldiamines with ketones in the presence of BF3-H2O is described. BF3-H2O plays a dual role, as an efficient non-oxidizing Bronsted acid catalyst as well as an effective solvent making the reaction more economic and environmentally safer. The reaction is simple, fast and convenient. (C) 2013 Elsevier B.V. All rights reserved.

An efficient green on‐water protocol for the synthesis of 2,2‐disubstituted 2,3‐dihydro‐1H‐perimidines is demonstrated. The reaction used safer p‐toluenesulfonic acid (PTSA) as a catalyst on water at 80°C, for 2 hours affording a novel method for the synthesis of various disubstituted perimidines in moderate to excellent yields.
