Four convergent syntheticapproaches to acetoxyenediynes have been explored to gain access to peyssonenynes A and B, which are natural products isolated from the red alga Peyssonelia caulifera. After optimization of the routes with a palmitic acid based model system, the synthesis of the peyssonenynes was completed by using, as the key steps, 1) Ni/Cu co-catalyzed cross-coupling of terminal alkynes
