The synthesis of 2H-benzopyrano[7,8-b][1,4]tetrahydrobenzodioxin-2-ones and 2H-benzopyrano [7,8-b][1,4]benzodioxin-2-ones is reported. This class of compounds, prepared with the aim of obtaining new monofunctional photosensitizing drug, appears to be ineffective upon UVA irradiation but shows a moderate but significant activity in the dark.
