Identification and determination of the absolute configuration of amorph-4-en-10β-ol, a cadinol-type sesquiterpene from the scent glands of the African reed frog Hyperolius cinnamomeoventris
Beilstein J. Org. Chem. 2023, 19, 167–175, doi:10.3762/bjoc.19.16
- chromatography; enantioselective synthesis; GC/MS; semiochemicals; Introduction Hyperolius cinnamomeoventris (Figure 1) is one of the largest species of reed frogs (Hyperoliidae), which are commonly found in Africa, south of the Sahara. Males of the Hyperoliidae possess a characteristic yellow gular patch on
- for species recognition and mate choice. In the related frog family Mantellidae such functions of volatiles from males have been demonstrated [3], but no behavioral experiments involving semiochemicals have been performed so far within the hyperolid family. H. cinnamomeoventris also served as a model
3-Acetoxy-fatty acid isoprenyl esters from androconia of the ithomiine butterfly Ithomia salapia
Beilstein J. Org. Chem. 2020, 16, 2776–2787, doi:10.3762/bjoc.16.228
- (Nymphalidae: Danainae) have hairpencils on the forewings (i.e., androconia) that disseminate semiochemicals during courtship. While most ithomiines are known to contain derivatives of pyrrolizidine alkaloids, dihydropyrrolizines, or γ-lactones in these androconia, here we report on a new class of fatty acid
Synthesis of disparlure and monachalure enantiomers from 2,3-butanediacetals
Beilstein J. Org. Chem. 2020, 16, 616–620, doi:10.3762/bjoc.16.57
- semiochemicals. They have been frequently found as pheromones in lepidopteran species of the families Noctuidae, Arctiidae, Lymantridae, Geometridae and Erebidae [1]. (3Z,9Z)-6S,7R-Epoxyheneicosa-3,9-diene, a constituent of the female sex pheromone of the moth Tetanolita mynesalis (Erebidae) [2] is a
Structure elucidation of female-specific volatiles released by the parasitoid wasp Trichogramma turkestanica (Hymenoptera: Trichogrammatidae)
Beilstein J. Org. Chem. 2014, 10, 767–773, doi:10.3762/bjoc.10.72
- about (volatile) semiochemicals playing a role in intraspecific communication [7][8][9][10][11]. Based on bioassays with Trichogramma turkestanica and extensive analytical investigations, two female-specific volatile compounds have been described as possible pheromone components and were tentatively
- semiochemicals representing saturated polydeoxypropionates typically show syn-configuration, suggesting general principles in enzymatic chain elongation [16][18], we hypothesized (2E,4E,6S,8S,10S)-tetramethyltrideca-2,4-diene or its enantiomer to be the natural product. To establish a syn,syn-configuration of
Stereoselective synthesis of trans-fused iridoid lactones and their identification in the parasitoid wasp Alloxysta victrix, Part I: Dihydronepetalactones
Beilstein J. Org. Chem. 2012, 8, 1246–1255, doi:10.3762/bjoc.8.140
- communication by volatile signals is considered to play a major role in interactions between these trophic levels, and some semiochemicals of the lower trophic levels such as oat plant and grain aphid have been identified [2][3][4]. However, there is nearly no information about the intra- and interspecific
- few others, the stereogenic center carrying the methyl group in the five-membered ring of iridoid lactones including insect semiochemicals [13][14][15] generally shows (S)-configuration. Only recently, two isomeric iridoid lactones showing (7R)-configuration have been identified from the Drosophila
A new phenylethyl alkyl amide from the Ambrostoma quadriimpressum Motschulsky
Beilstein J. Org. Chem. 2011, 7, 1342–1346, doi:10.3762/bjoc.7.158
- , many research efforts have concentrated on chemical communication among beetles [3][4][5][6]. Only a limited number of semiochemicals [7][8][9][10][11][12][13] are known in leaf beetles. To the best of our knowledge, fatty acid amides from terrestrial insects have not been reported so far. In addition
