reacted via ESIPT to both 9- and 10-positions, giving rise to two types of intermediates, quinonemethides (e.g., 29) and zwitterions (e.g., 30). These intermediates are trapped by solvent (water or methanol) giving additionproducts that can readily revert back to starting material. However, on extended photolysis, the products that are isolated can best be rationalized as being due to competing elimination
