Total syntheses of five naturally occurring polyacetylenes from three different plants are described. These natural products have in common anE,Z-configured conjugated diene linked to a di- or triyne chain. As the key method to stereoselectively establish theE,Z-diene part, an ester-tethered ring-closing metathesis/base-induced eliminative ring opening sequence was used. The results presented herein do not only showcase the utility of this tethered RCM variant but have also prompted us to suggest that the originally assigned absolute configurations of chiral polyacetylenes fromAtractylodes macrocephalashould be revised or at least reconsidered.
