Structural elucidation of two new acetylenic polyenes, laurencenyne 5 and neolaurencenyne 6 isolated from Laurencia okamurai, together with their syntheses, was achieved, suggesting that laurencenyne 5 was a possible precursor of various nonterpenoid C₁₅-compounds in the marine red algae of genus Laurencia.
