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.

From the red alga Laurencia okamurai four new C15 acetylenic polyenes, laurencenyne 6, neolaurencenyne 8, and trans-neolaurencenyne 9 have been isolated and their structures were elucidated by chemical and spectral means.Synthesis of these four compounds has been made to confirm their structural and stereochemical assigments.Biogenesis of laurencenyne 6 and trans-laurencenyne 8 was discussed.
