title = "The effect of chromophore transposition on the stereochemical outcome of the intramolecular dioxenone photocycloaddition reaction",
abstract = "Transposition of the chromophore leads to complete reversal of previously observed stereoselectivities in the intramolecular dioxenone photocycloaddition. A proposal to explain this change in stereoselectivity in presented, and the facile transannular reaction of the photoaddition/fragmentation product derived from the transposed photosubstrate 5 is described.",
