The construction of new C–N chemical bonds through co‐condensation reaction in water media as sole solvent, especially without the use of any metal catalyst has undergoes green protocols. Herein, we describe a water‐mediated and metal‐free mild protocol for easily accessing of structurally and electronically diverse 1,5‐benzodiazepine analogous by using biodegradable naturally occurring itaconic acid (20 mol%) in 30 minutes with excellent yields. The simplicity in reaction operation, reusability of the catalytic system and simple filtration to get the desired product make this reaction as “green synthetic pathway” upto multi gram scale level.
