The built-in ortho-and para-QM (QM = quinone methide) moieties in benzo[cd]azulen-3-ones account foran easy switch between the bridged 10π-and 6π-aromatic systems in organic synthesis. We report conjugate additions, oxidative nucleophilic substitutions of hydrogen, and reversible Michael additions under very mild conditions. In the presence of thiol nucleophiles the protonated σH-adducts could be isolated and characterized. The typical preference for either the o- or p-QM moiety led to high regioselectivity. Furthermore, the inhibitory potency of the novel benzo[cd]azulenes against the human Pim-1 kinase was evaluated.
