Abstract
The gold-catalyzed cycloisomerization of tetrasubstituted [3]-cumulenols has been investigated. Overall, two main pathways are followed. In the presence of a gold(III) catalyst, a dehydration process prevails giving diastereomerically pure dienynes while gold(I) catalysts favor the cycloisomerization to provide trisubstituted furan derivatives.
