Indiummediated coupling of allylic bromide with acyloyl-imidazoles or pyrazoles in aqueousmedia gives the corresponding tertiary alcohols or ketones in good yield. The reaction provides a facile regioselective synthesis of β,γ-unsaturated ketones and its usefulness is demonstrated by the synthesis of the monoterpene artemesia ketone.
