title: Synthesis of crossed [2 + 2] photocycloadducts: a novel approach to the synthesis of bridged bicyclic alkenes.
abstract: [reaction: see text] A solution to the synthesis of "crossed" intramolecular [2 + 2] photocycloadducts has been achieved. Through the use of a temporary heteroatom linker, the equivalent of a crossed photocycloadduct can be accessed at the expensive of the normal "straight" adduct. Selectivity as high as 94:6 for the "crossed" adduct has been observed.
