摘要
The in situ generated prenylzinc reagent from the reaction of zinc with prenyl bromide has been shown to undergo a new type of alpha-regioselective addition reaction with a wide range of esters that affords gem-bisprenyl structures. The reaction proceeds under mild conditions to provide alpha,alpha'-adducts with complete alpha-regioselectivity. A mechanism with the consideration of the steric factors is proposed to account for the regioselective results.
