(3Z,9Z,6S,7R)-6,7-epoxy-3,9-octadecadiene (1) and (3Z,9Z,6R,7S)-6,7-epoxy-3,9-octadecadiene (2) have been stereoselectively synthesized in eight steps from 2-pentyn-1-ol with an overall yield of 8%. The key steps involved the Sharpless asymmetric dihydrox
Pheromone Bouquet of the Dried Bean Beetle, Acanthoscelides obtectus (Col.: Chrysomelidae), Now Complete

Male-specific volatile components, released by the dried bean beetle, Acanthoscelides obtectus, were identified as methyl (E,R)-2,4,5-tetradecatrienoate, methyl (2E,4Z,7Z)-2,4,7-decatrienoate, methyl (2E,4Z)-2,4-decadienoate, octadecanal and the sesquiterpenes (3Z,6E)- and (3E,6E)-α-farnesene. In olfactometer bioassays, pure methyl (E,R)-2,4,5-tetradecatrienoate was only weakly attractive to unmated females. However, a blend of the six identified compounds released in physiologically relevant ratios and doses proved to be as active as headspace odours collected from live males.
A Modular, Enantioselective Synthesis of Resolvins D3, E1, and Hybrids

Resolvins D3 and E1 are important signaling molecules in the resolution of inflammation. Here, we report a convergent and flexible strategy to prepare these natural products using Hiyama-Denmark coupling of five- and six-membered cyclic alkenylsiloxanes to connect three resolvin fragments, and control the stereochemistry of the natural product (Z)-alkenes. The modular nature of this approach enables the synthesis of novel resolvin hybrids, opening up opportunities for more-extensive investigations of resolvin biology.

The invention relates to a natural [...] pheromone component novel synthesis method, in particular relates to a tea canker-worm pheromone (Z, Z, Z) - 3, 6, 9 - eighteen carbon triene synthetic method, it has [...], is non-toxic and harmless, which belongs to the field of drug synthesis. The invention uses inexpensive and easily obtained a halopropynyl alcohol as the reaction of the starting material, in order to iodo reagent catalytic coupling reaction as a key step, after six-step reaction, smooth synthetic tea canker-worm pheromone (Z, Z, Z) - 3, 6, 9 - eighteen carbon triene, the operation is simple, low cost, easily obtained and cheap materials, mild reaction conditions, high yield, the large scale preparation.
