摘要：

The influence of substituents on the regio- and stereochemistry of the intramolecular [2+2] photocycloaddition of compound 1-8 has been studied. All photoadducts are formed via parallel approach and syn-addition. The endo/exo ratio was used as indicator for the structure of the diradical intermediates.
