C. Zhang et Xc. Guo, INTRAMOLECULAR HYDROGEN-BOND EFFECT IN META-CYCLOADDITION OF ARENE TOOLEFIN, Synthetic communications, 24(21), 1994, pp. 3157-3165
The intramolecular meta-photocycloaddition of bichromophores 1a and 1b
is examined and the observed stereochemistry of cycloaddition is rati
onalized in terms of hydrogen bond effect introduced by the 3-hydroxy
group in the 5-phenylpent-1-ene skeleton.
