An efficient bismuth triflate catalyzed [1,3] rearrangement of aryl 3-methylbut-2-enyl ethers has been developed. The reaction proceeds rapidly and affords the corresponding para- and ortho-prenylated phenols and naphthols in moderate to good yields (up to 86%). ortho-Prenylphenols are immediately cyclized under the reaction conditions to the corresponding chroman derivatives.
