Cutleria multifida

Multifidene is a sperm cell-attracting substance released by the female of a species of brown algae (Cutleria multifida). The constitution of multifidene is... 

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. 

A salt-free ylide has been used to obtain 95 % of the cw-product (67) in the synthesis of a constituent of the androgamete attractant of Cutleria multifida ...

The utilization of pericyclic reactions of thermolabile intermediates has been extended to 7-methylcyclooctatetraene, a pheromone from the brown alga Cutleria multifida. Boland and Pohnert have reported the electrolytic ring closure of l,3Z,5Z,7E-nonatriene to afford the cyclooctatetraene derivative [52]. The biomimetic synthesis of this pheromone lends additional support to the suggested use of pericyclic reactions in the biosynthesis of the algal gynogametes.
