摘要：

An intermediate of the anellation reaction of phenols and 1,3-dienes could be detected, isolated and characterized as the hydroarylation product. The other conceivable intermediate, the hydroaryloxylation product, was prepared via Pd-catalysis and converted under the conditions of the gold catalysis, too. Under exactly the same conditions a very fast Claisen rearrangement took place delivering the formal hydroarylation product as well. After this fast intermolecular formation of the intermediate (formed either directly via the hydroarylation pathway or via a hydroaryloxylation/Claisen rearrangement sequence) the subsequent intramolecular reaction leading to the product turned out to be significantly slower. The major product is the cis-diastereomer (cis-3/trans-3 = 12:1). (C) 2015 Elsevier B.V. All rights reserved.
