When both ortho positions on the aromatic ring are blocked, the enolization of the Claisen
rearrangement product is impossible.In this case two sequential [3,3]-shifts occur, affording a
trisubstituted phenol.Starting from the following allyl aryl ether, draw the arrow formalism for
both [3,3] shifts, showing the intermediates and the final product.
