G. Dyker et al., SYNTHESIS AND PALLADIUM-CATALYZED TRANSFORMATION OF AN ANNELATED BARRELENE, Journal of the Chemical Society. Perkin transactions. I, (8), 1997, pp. 1163-1166
The annelated barrelene 8 is easily accessible in a three-step reactio
n procedure from simple starting materials. An intermolecular palladiu
m-catalysed arylation at the strained tetrasubstituted double bond of
the barrelene finally leads to polycyclic hydrocarbons.
