Abstract
The total synthesis of multifidene, a sex pheromone found in brown algae, is described. The synthesis features the highly enantioselective and diastereoselective addition reaction of an aldehyde to a nitroolefin in the presence of a Hayashi–Jørgensen catalyst and a Nef reaction initiated by visible light irradiation. These key reactions enabled the 11-step synthesis from commercially available compounds. The synthetic pheromones are examined with gametes.

Abstract
During the cultivation of the edible mushroom Fomitopsis betulina on agro-industrial side streams, a pleasant flavor strongly reminiscent of pineapple was perceived. Aroma extract dilution analyses identified two flavor components with a distinct pineapple odor. On the basis of mass spectrometric data, a Wittig reaction of (E)-penta-2,4-dien-1-yltriphosphonium bromide with ethyl levulinate was conducted. The resulting (5E/Z,7E,9)-decatrien-2-ones were identical to the compounds isolated from the fungal culture. Some structurally related methyl ketones were synthesized, confirmed by nuclear magnetic resonance and mass spectrometry, and their odor was characterized. The lowest odor threshold and most characteristic pineapple-like odor was found for (5Z,7E,9)-decatrien-2-one. Global minimum energy calculation of the methyl ketones and the comparison to (1,3E,5Z)-undecatriene, a character impact compound of fresh pineapple, showed that a chain length of at least 10 carbon atoms and a terminal double bond embedded in a "L"-shaped conformation were common to compounds imparting an intense pineapple-like odor. Both (5E/Z,7E,9)-decatrien-2-ones have not been described as natural flavor compounds.

Abstract
The essential oils of the flowers, leaves and stems of Senecio polyanthemoides Sch. Bip. Samples collected from two different localities within the city of uMhlathuze, KwaZulu-Natal Province (South Africa) were isolated by hydrodistillation and analyzed using GC and GC/MS. Twenty-six constituents were identified, representing an average of 86.0 - 99.6% of the total oil composition. The chemical profile reveals the dominance of monoterpenoid compounds, although some quantitative variance was noticed. The main constituents of the oils were limonene (3.1 - 43.0%), p-cymene (4.9-36.3%), beta-selinene (1.3-32.7%), alpha-pinene (1.8-21.4%), beta-pinene (7.6-16.5%) and 1,8-cineole (9.3-11.4%), caryophyllene oxide (4.1-13.4%) and humulene epoxide II (8.6-10.3%).

Abstract
Female gametes of marine brown algae release and/or attract their conspecific males by chemical signals. The majority of these compounds are unsaturated, nonfunctionalized acyclic, and/or alicyclic C11 hydrocarbons. Threshold concentrations for release and attraction are generally observed in the range of 1-1000 pmol. The blends may contain various configurational isomers of the genuine pheromones as well as mixtures of enantiomers. Higher plants produce the C11 hydrocarbons from dodeca-3,6,9-trienoic acid; brown algae exploit the family of icosanoids for biosynthesis of the same compounds. The biosynthetic routes comprise several spontaneously occurring pericyclic reactions such as [3.3]-sigmatropic rearrangements, [1.7]-hydrogen shifts, and electrocyclic ring closures. All pheromones are (a)biotically degraded by ubiquitous oxidative pathways involving singlet oxygen or hydroxyl radicals, which may be produced through the agency of heavy metals, huminic acids, or light.

Abstract
Unsaturated C8 and C11 hydrocarbons act as chemical signals (chemotaxis) during sexual reproduction of many marine brown algae. One of these compounds, namely (+)-(6S)-6-(1Z-butenyl)cyclohepta-1,4-diene (= ectocarpene) is also formed as a major hydrocarbon by the flowering plant Senecio isatideus (Asteraceae). On administration of enantiospecifically labelled (8R)- or (8S)-[7,8-2H2]trideca-3,6,9-trienoic acid instead of the natural precursor dodeca-3,6,9-trienoic acid to this plant, the artificial C12 analogue of ectocarpene is formed. Mass spectroscopic analysis of the metabolites revealed this process to be enantiospecific for the C(8)-HRe atom of the precursor acid. The stereochemical course of the overall reaction is in agreement with a precise, U-shaped embedding of the trienoic acid into the active center of the enzyme(s) and Re-attack onto a hydrogen at the C(8) methylene group of this precursor. The reactive intermediate cyclizes by pi-orbital interaction between C(4) and C(6) of the acid and is accompanied by decarboxylation. The first product is a thermally unstable (1S,2R)-cis-1-(1E,3Z-hexadienyl)-2-vinylcyclopropane, which immediately rearranges to (+)-(6S)-ectocarpene (homo-Cope rearrangement). The present work provides first experimental evidence for a homo-Cope rearrangement as a naturally occurring electrocyclic reaction.

Abstract
Odd numbered 1-alkenes, such as 1-pentadecene or 1,8,11,14-heptadecatetraene are formed from palmitic or linolenic acid by fragmentative decarboxylation. Incubation studies with germinating safflower (Carthamus tinctorius) and (2R,3R)-12-phenyl[2,3-2H2]dodecanoic acid, (2S,3S)-12-phenyl[2,3-2H2]dodecanoic acid, (2R)-12-phenyl[2-2H]dodecanoic acid and (2S)-12-phenyl[2-2H]dodecanoic acid instead of the natural alpha-linolenic acid precursor revealed the fragmentation to be an overall anti elimination of the 3-pro(S) hydrogen and the carboxyl group (anti-periplanar transition state geometry). Externally offered 3-hydroxy acids are not fragmented to 1-alkenes. The most probable mechanistic alternatives are in agreement with abstraction of the 3-pro(S) hydrogen as a radical followed by electron transfer and fragmentation, or transient insertion of oxygen into the 3-pro(S) C-H bond and subsequent fragmentation into an 1-alkene and CO2 after appropriate activation. The mechanism seems to be of general importance for the biosynthesis of vinylic substructures of natural products from oxygenated precursors.

Abstract
Uneven numbered 1-alkenes, such as 1-pentadecene, 1-heptadecene, 1,8-heptadecadiene, 1,8,11-heptadecatriene and 1,8,11,14-heptadecatetraene are the predominant hydrocarbons in germinating safflower (Carthamus tinctorius L.). According to their chain length and positions of double bonds they are derived from palmitic, stearic, oleic, linoleic or linolenic acid, respectively. This has been proved by administration of synthetic alpha-, beta-, or gamma-deuterated 12-phenyldodecanoic acids to germinating safflower. Mass spectrometric analysis of the resulting deuterium-labelled 11-phenyl-1-undecenes shows that only a single hydrogen from C-3 and carbon dioxide from C-1 of the precursor fatty acid is lost during vinyl group formation. A strong isotope effect (kH/kD greater than or equal to 10) during the conversion of racemic 12-phenyl[3-2h]dodecanoic acid to 11-phenyl-1-[2-2H]undecene is consistent with an initial enzymatic attack on a non-activated hydrogen at C-3 accompanied by simultaneous fragmentation into the respective 1-alkene and carbon dioxide. Mechanisms, based on ionic or radical abstraction of a hydrogen from C-3 of the fatty acid, followed by decarboxylation are discussed. The results are applicable to the formation of various vinylic substituents in natural products such as porphyrins, acetylenic hydrocarbons, pheromones from marine brown algae and terpenoids.
