on the aromaticcore and a tethered alkyl moiety provides a straightforward approach to access these scaffolds; however, such a strategy is often hampered by the need of special reactive groups and/or less compatible cyclization conditions. It would be synthetically appealing if a common native functional group can be used as a handle to enable a general C–H annulation with diverse aromatic rings.

This paper describes the Bronsted acidmediatedreaction of methylenecyclopropanes with various arenes to give the corresponding doubleFriedel-Craftsreaction products (cyclized products) under mild conditions. A plausible reaction mechanism is discussed on the basis of deuterium labeling and control experiments. (c) Wiley-VCH Verlag GmbH & Co, KGaA, 69451 Weinheim, Germany, 2005.
