  Identification of a novel moth sex pheromone inEriocrania cicatricella (Zett.) (Lepidoptera: Eriocraniidae) and its phylogenetic implications

  摘要：

  Extracts from different body parts of adult female Eriocrania cicatricella (Zett.) were tested for electrophysiological activity on conspecific male antennae. Extracts from the Vth abdominal segment, containing a pair of exocrine glands, elicited the largest electroantennographic response when compared to extracts of other body parts. Female extracts were analyzed by gas chromatography with simultaneous flame ionization and electroantennographic detection (EAD). The EAD active peaks were identified as (Z)-4-hepten-2-one, (2R)-heptane-2-ol, and (2R)-(Z)-4-hepten-2-ol by coinjection on a gas chromatography and by comparison of mass spectra with those of synthetic standards. In field tests, a blend of these three pheromone components was highly attractive to conspecific males, and a subtractive assay confirmed that the unsaturated alcohol is the major pheromone component, whereas no definite behavioral activity could be assigned to the ketone or the saturated alcohol. A bait containing the two alcohols with S-configuration was attractive to male E. sparrmannella (Bosc), whereas no males of E. cicatricella were found in these traps. The sex pheromone compounds in E. cicatricella are chemically similar to pheromones reported in Trichoptera and they are produced in homologous glands.

• Stereoselective expoxidation of allylic and homoallylic alcohols with 30% hydrogen peroxide catalyzed by tungstic acid in buffered media
  作者：Denis Prat、Bernard Delpech、Robert Lett

  日期：1986.1

  The aqueous tungstic acid-catalyzed hydrogen peroxide epoxidation of allylic alcohols affords the same major diastereoisomer as the VO(acac)2/tBuOOH system with quite comparable stereoselectivities. In contrast, epoxidation of homoallylic alcohols appears to be much less stereoselective.

  钨酸催化的烯丙醇过氧化氢环氧化可提供与VO（acac）2 / tBuOOH体系相同的主要非对映异构体，且具有相当的立体选择性。相反，均烯丙基醇的环氧化似乎立体选择性低得多。

  The chlorosulfides 1 or 2 react with silyl enol ethers in presence of anhydrous zinc bromide to give mainly the corresponding syn products 4 or 6 respectively. The high syn selectivity of these reaction is explained by nucleophilic addition to a Chelated Chiral thioniun ion.

  In tandem reactions, cyclopropyl carbinols are obtained from allyloxylithium or -magnesium intermediates, generated in situ by alkylation of conjugated aldehydes, ketones, and esters as well as from allyl carboxylates or vinyloxiranes. Using this methodology, numerous fragrance ingredients and their precursors were efficiently converted to the corresponding cyclopropyl carbinols.
