<p>Three-component reaction in one pot transformation of aldehydes, ethylacetoacetate and o-phenylenediamine was employed for the synthesis, under solvent-free, of 1,5-benzodiazepine derivatives using fertilizers mono-ammonium phosphate (MAP), di-ammonium Phosphate (DAP) and triple super phosphate (TSP) as safe, clean, and recyclable catalysts. The synthesis method seems to be operationally simple and provides access to a variety of 1,5-benzodiazepines with excellent yields in a short reaction
