AbstractThe results of our investigations on the preparation of 3a,8a‐dihydroxyindeno[1,2‐d]imidazole derivatives via reaction of thiourea, ninhydrin, and alkyl/benzyl chlorides in aqueous ethanol and under convenient conditions is reported. On the other hand, when guanidinium chloride was used instead of thiourea, the reaction mixtures reached with unexpected products; 2,2‐dialkoxy‐1H‐indene‐1,3(2H)‐diones.
