and Thermal Sigmatropic Rearrangements of 2-Pentadienyloxypyridine N-Oxides

2-Pentadienyloxypyridine N-oxides (3) are smoothly transformed on heating into N-pentadienyloxy-2-pyridones (4) and N-hydroxy-5-pentadienyl-2-pyridones (5).These reactions are shown to be regiospecific and are believed to proceed in a concerted fashion.Th

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.

LEWIS ACID MEDIATED CLAISEN-TYPE REARRANGEMENT OF ARYL DIENYL ETHERS

In the presence of BF3.OEt2 aryl dienyl ethers were rearranged under mild conditions to afford dienyl phenols in good yields.
