Lewis-Acid-Assisted "Tandem Claisen Rearrangement": Application to the Synthesis of a New Type of Macrocycle Containing Phenolic Moieties.

-The synthesis of a new type of macrocycles with four phenolic hydroxyl groups (VIII) involving a new strategy for the tandem Claisen rearrangement (VII) → (VIII) by use of Et 2 AlCl and 2-methyl-2-butene is given. -(UZAWA, H.;
