Novel ninhydrin–creatinine heterocyclic condensation products ( 3–5 ) were synthesized under different solvent conditions. The compound 2‐(2‐amino‐1‐methyl‐4‐oxo‐4,5‐dihydro‐1 H ‐imidazol‐5‐yl)‐2‐hydroxy‐1 H ‐ind‐ene‐1,3(2 H )‐dione ( 3 ) was formed by reacting ninhydrin ( 1 ) with creatinine ( 2 ) in the presence of sodium acetate in acetic acid. The same reactants afforded the zwitterionic compound 4 when the reaction was carried out in water, and a novel oxadiazine ring system (product 5 ) was generated when benzene was used as solvent.
