The use of enynes in transition-metal-mediated cycloisomerizations form the basis of an efficient and popular method for the preparation of exocyclic 1,3-dienes. Depending upon the nature of the substituents about the unsaturated bonds of the starting materials, vinylic conjugated cycloalkenes may be generated as the main byproducts (see Section 46.5.4).
