and intramolecular hydroaryloxylation were catalyzed by aluminumchloride. The second aromatic Claisen rearrangement step was also studied under thermal conditions to give mostly isomerized exocyclic compounds. The precursor endocyclic compounds were synthesized by thermal [3,3] sigmatropic rearrangement of the corresponding sulfide.Key words: aluminumchloride, sequential Claisen rearrangement, hydroaryloxylation
