Intramolecular hydrogen bond effect in meta-cycloaddition of arene to olefin

Zhang,Guo

, p. 3157 - 3165 (1994)

The intramolecular meta-photocycloaddition of bichromophores 1a and 1b is examined and the observed stereochemistry of cycloaddition is rationalized in terms of hydrogen bond effect introduced by the 3-hydroxy group in the 5-phenylpent-1-ene skeleton.
