Abstract:		"Neodictyoprolenol [(-)-(3S)-(1,5Z,8Z)-undecatrien-3-ol] and dictyoprolenol [(-)-(3S)-(1,5Z,8Z)-undecadien-3-ol]), which had been proposed as possible biosynthetic intermediates of the sex pheromones of marine brown algae such as dictyopterene B [(-)-trans-1-((1'E,3'Z)-hexadienyl)-2-vinylcyclopropane], D' [(+)-6-((1'Z)-butenyl)-1,4-cycloheptadiene] and C' [(+)-6-butyl-1,4-cycloheptadiene], were again identified in the essential oils from Dictyopteris prolifera, D. latiscula, and in D. undulata, together with the C11-related volatile compounds such as neodictyoprolene, dictyoprolene and dictyopterenes. Incubation of D. prolifela preparation with racemic neodictyoprolenol and dictyoprolenol as substrates showed (S)-enantioselective decreases of the added substrates and increases in dictyopterenes. From these results, a possible pathway to form dictyopterenes is discussed"
