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