coumarin fused spirooxindole derivatives, making this strategy very useful in diversity-oriented synthesis (DOS). This synthesis was established to follow the group-assistant-purification chemistry process (GAP) avoiding traditional chromatography, whereupon recrystallization purifications appear to be a very good alternative to the traditional classical methods. The aqueous reactionmedium, dual role
