TLDR
Examples of total syntheses in which metathesis reactions of olefins, enynes, and alkynes played a crucial role and which imparted to these endeavors certain elements of novelty, elegance, and efficiency are highlighted.Abstract:
With the exception of palladium-catalyzed cross-couplings, no other group of reactions has had such a profound impact on the formation of carbon-carbon bonds and the art of total synthesis in the last quarter of a century than the metathesis reactions of olefins, enynes, and alkynes. Herein, we highlight a number of selected examples of total syntheses in which such processes played a crucial role and which imparted to these endeavors certain elements of novelty, elegance, and efficiency. Judging from their short but impressive history, the influence of these reactions in chemical synthesis is destined to increase.read more
