  Sex pheromone of caddisflyHesperophylax occidentalis (Banks) (Trichoptera: Limnephilidae)

  摘要：

  The main component of the sex pheromone of the caddisfly Hesperophylax occidentalis (Banks) (Trichoptera: Limnephilidae) was identified as 6-methylnonan-3-one (enantiomeric composition has not yet been determined). Extracts of adult females elicited strong electroantennogram (EAG) responses from adult male antennae, but elicited significantly smaller EAG responses from adult female antennae. Extracts of adult males did not elicit appreciable EAG responses from antennae of either sex. Racemic 6-methylnonan-3-one was synthesized and elicited EAG responses from male antennae as strong as those obtained with female extracts. In field tests with baited sticky traps near lakes and streams, traps baited with synthetic racemic 6-methylnonan-3-one caught significantly more males than control traps. Female adults contained approximately 1 mu g of 6-methylnonan-3-one per individual. Related ketones and alcohols of other chain lengths were also tentatively identified, being present in tiny amounts in female extracts. Extraction of different body parts showed that 6-methylnonan-3-one occurs only in a region near the intersegmental membrane between the fourth and fifth abdominal sternites of the female (no discrete glands were observed). Extracts of males did not contain 6-methylnonan-3-one, nor did pupae of either sex.

  Do enzymes recognise remotely located stereocentres? Highly enantioselective Candida rugosa lipase-catalysed esterification of the 2- to 8-methyldecanoic acids

  摘要：

  Several racemic methyl decanoic acids have been synthesised and Successfully resolved in esterification with 1-hexadecanol at a(w)=0.8 in cyclohexane using immobilised Candida rugosa lipase (CRL) as the catalyst. The enantiomeric ratios (E=2.8-68) obtained were surprisingly high even when the methyl group was as remotely located as in 8-methyldecanoic acid (E=25). Interestingly, the lipase shows enantiopreference for the S-enantiomer when the methyl group is located on even numbered carbons i.e. for the 2-,4-,6- and 8-methyldecanoic acids and to the R-enantiomer when the methyl group is located on uneven numbered carbons i.e. for the 3-,5- and 7-methyldecanoic acids.
