Significance
Stereoselective syntheses of the cyclopentyl unit via novel enyne-type cyclizations are described. This is a powerful method for diastereoselective preparation of highly functionalized precursors which can be further synthetically elaborated. The authors have shown a superior generality of the method employing various enynes with equal efficiency. In addition, they have demonstrated the usefulness of the dienes obtained by producing fused bicyclic products via quantitative ring-closing metathesis.
