Lewis Acid Mediated Claisen-Type Rearrangement of Aryl Dienyl Ethers

Rearrangement of aryl pentadienyl ethers in the presence of BF3*OEt2 affords pentadienyl phenols in good yields without formation of the corresponding rearranged products.The mechanism of this rearrangement was studied by deuterium labeling and cross-coupling reactions.The scope and limitations of the rearrangement are discussed.
