A new synthesis of the acetate of octadeca-trans-2,cis-13-dien-1-ol based on the alkylation of propargyl alcohol with pentadec-cis-10-enyl bromide, obtained from the readily accessible decamethylene bromohydrin, has been effected.

Two Melittini species, Macroscelesia japona and M. longipes (Lepidoptera: Sesiidae), are native to Japan, but occupy different localities as their host plants seldom grow together. The contents of the sex pheromone gland of adult females of both species, obtained after rearing larvae collected from the field, were investigated by gas chromatograph-electroantennogram detection (GC-EAD) and gas chromatograph-mass spectrometry (GC-MS) analyses. Two GC-EAD-active components were found in a crude extract of M. japona female pheromone gland, and identified as (2E,13Z)-2,13-octadecadien-1-ol (E2,Z13-18:OH) and (2E,13Z)-2,13-octadecadienal (E2,Z13-18:Ald). The average ratio of these two components was about 1:10. In the field, M. japona males were attracted to traps baited with E2,Z13-18:Ald alone, but the strongest attraction was observed with a 1:100 mixture of E2,Z13-18:OH and E2,Z13-18:Ald. The same two components were found in extracts of M. longipes females, but in a markedly different ratio. Male M. longipes were attracted most strongly to lures containing a 20:1 mixture of E2,Z13-18:OH and E2,Z13-18:Ald, although some males were also attracted to lures with E2,Z13-18:OH alone. Although the two species do not generally occur in sympatry, our data indicate that, in the event of overlap, cross attraction of the two species is unlikely.

The recognition of the dual binding mode of propargyl and allyl alcohols to [Cp*Ru] fragments fostered the development of a highly regioselective intermolecular Alder-ene-type reaction of alkynes with 1,2-disubstituted alkenes. The increased substrate scope opens new perspectives in stereochemical terms. As the loaded catalyst is chiral-at-metal, stereochemical information is efficiently relayed from the propargylic site to the emerging C?C bond. This interpretation is based on the X-ray structure of the first Cp*Ru complex carrying an intact enyne ligand, and provides valuable insights into bonding and activation of the substrates. Computational data draw a clear picture of the principles governing regio- and stereocontrol.
Synthesis and characterization of 3,13- and 2,13-octadecadienyl compounds for identification of the sex pheromone secreted by a clearwing moth, Nokona pernix

Several geometrical isomers of 3,13- and 2,13-octadecadien-1-ols and their acetates were synthesized starting from 1,8-octanediol or 1,9-nonanediol utilizing acetylene coupling reactions. In addition to commercially available compounds, all geometrical isomers of each dienyl compound were analyzed by NMR and GC-MS to accumulate chemical data for studies of sex pheromones secreted from clearwing moths classified into the family Sesiidae of Lepidoptera. Although acetoxy derivatives of the 3,13- and 2,13-dienes showed almost the same mass spectra, the alcohols were distinguished by comparing the relative intensities of [M - 18]+ at m/z 248, indicating direct differentiation of the two positional isomers without derivatization. Furthermore, each geometrical isomer eluted from a high-polar GC column with a different retention time. Base on these data, a pheromone gland extract of a sesiid moth, Nokona pernix, was analyzed by GC-EAD and GC-MS, and two EAG-active components were identified, viz., the (3E,13Z)- and (3Z,13Z)-isomers of 3,13-octadecadien-1-ol in a ratio of 9:1. In the field, the synthetic compounds mixed in 9:1 ratio attracted N. pernix males well, while a single component scarcely attracted the males. The number of attracted males peaked in the middle of June, and a small second peak was observed in August.

, p. 845 - 848 (2008/02/09)
(equation presented) A new, convergent synthesis of (E,Z)-2,13-octadecadienyl acetate (1) and (E,Z)-3,13-octadecadienyl acetate (2), the two key components of the leopard moth Zeuzera pyrina, from 2-chloromethyltetrahydrofuran in good overall yields and stereomeric purity is reported. The synthesis of both components utilizes the common intermediate sulfone 12 as a convenient building block to be coupled with iodoacetylenic derivatives 9 or 17 in the key step.

, p. 621 - 624 (2007/10/02)
The Wittig-Horner reaction of ethoxycarbonylmethylenetriphenylphosphorane or ethyl diethylphosphonoacetic acid with cis-11-hexadecenal and the modified Knoevenagel reaction of this aldehyde with malonic acid gave the ethyl ester of trans-2,cis-13-octadecadienoic acid and trans,cis-13-octadecadienoic acid, which upon reduction and acetylation were converted into trans-2,cis-13- and trans-3-cis-13-octadecadien-1-yl acetates, which are components of the sex pheromone of Synanthedon tipuliformis (Lepidoptera, Sisiidae).
