The epoxidation of substituted dibenzo[a,kl]xanthenes using hydrogen peroxide was investi-gated. By optimizing the reaction conditions, including temperature, reaction time, solvent and the amount of oxidant, yields of 91%~98% could be achieved at room temperature in a base system

Key words: dibenzo[a,kl]xanthenes, epoxidation, synthesis, hydrogen peroxide
