Multifidene

Multifidene is a sperm cell attracting substance released by the female of a species of brown algae Cutlena rnultifida) The constitution of multifidene is... [Pg.322]

Fucoserraten, ectocarpen, and multifidene are sex pheromones produced by marine brown algae. What are their systematic names (The latter two are a bit difficult make your best guess.)... [Pg.208]

Recent advances in gas chromatographic separations of enantiomers allow precise determination of the enantiomeric purity of the algal pheromones. The czs-disubstituted cyclopentenes, such as multifidene, viridiene, and caudoxirene, are of high optical purity [ 95% enantiomeric excess (e.e.)] whenever they have been found (32,33). The situation is different with the cyclopropanes and the cycloheptadienes, as shown in Table 2 and Figure 1. Hormosirene from female gametes or thalli of... [Pg.101]

Multifidene (69), a major constituent of the essential oil of Cutleria multifida, has been prepared by a method based uptm rDA cleavage of adduct (68) (equatitm 36). The synAesis of (69) combines a high degree of stereoselectivity with broad variability, giving easy access to analogs of multifidene. [Pg.563]
