The absolute configuration of the gamete-releasing and -attracting pheromone 2-vinyl-3-(5'-vinylcyclopent-2'-enyl)oxirane ( = (+)-caudoxirene; (+)-1) of the marine brown alga Perithalia caudata is established as (2R,3R,1'S,5'S).Highly diastereoselective syntheses and the biological activities of three diastereoisomers of 1 are described.Compound (+)-(2R,3R,1'S,5'S)-1 is the first fully characterized epoxypheromone from marine brown algae (Phaeophyceae).

cis-3-(trans-1,2-Epoxybut-3-enyl)-4-vinylcyclopentene ((+/-)-4, caudoxirene) is a new gamete-releasing and gamete-attracting pheromone from the marine brown alga Perithalia caudata (Sporochnales).The key step of its synthesis is the diastereoselective alkylation of the aldehyde 8 with the titanium reagent 9 to yield the erythro-β-hydroxy sulfide 10 which affords 4 on sequential treatment with Me3O*BF4 and aq.NaOH.The lowest effective concentration of (+/-)-4 for gamete-release is found at 1.4 x 10-11 mol/l seawater.
