functionalized intermediates, such that the olefinic termini of the side chains could enter into intramolecular carbon−carbon bond formation. In no example was ring closure observed to operate. Instead, the strategically placed π-bonds were seen to migrate internally to the chain in select examples. Although the pivotal transformations failed, the deployment of a number of useful stereocontrolled reactions
