A metal-free, photo-induced CâO bond formation methodology was developed to construct tetrahydroxanthones. This mild and efficient methodology was based on intramolecular oxygen trapping of the reactive species produced by photolytic activation of a CâCl bond. We believe this method could be used in the synthesis of related xanthone-type natural products.
