A wide range of α-prenylated alcohol derivatives could be obtained in good yields by highly α-regioselective zinc-mediated prenylation of various aldehydes and ketones with prenyl bromide at 120C in HMPA. By simply altering the reaciton solvent and temperature, the method allows the achievement of a highly notable opposite regiocontrol, providing the expected regiochemical product.
