	An efficient, environmentally friendly protocol was developed for the synthesis of 4-substituted 1,5-benzodiazepines via a one-pot three-component reaction. o-Phenylenediamines, dimedone, and aldehydes were reacted in the presence of silica-supported orthophosphoric acid (H3PO4 &amp;amp; centerdot;SiO2) as an environmentally friendly, heterogeneous catalyst at 70 degrees C to produce 4-substituted 1,5-benzodiazepines. High to excellent yields, metal-free, environmentally friendly, reusable catalyst, and faster reactivity are the notable features of the developed protocol.&lt;/p&gt;
