Geographic variation in the sex pheromone of the Asian corn borer, Ostrinia furnacalis (Guenee), was surveyed in populations sampled at four locations ranging from 39.7°N to 32.9°N in Japan. The sex pheromone of the three northern populations was composed of (E)- and (Z)-12-tetradecenyl acetates with a mean E proportion of 36-39%. The southernmost population (Nishigoshi) had the same components but with a significantly higher E composition of 44%. The frequency distribution of the E ratio in the Nishigoshi population exhibited a small peak near 38% and a major peak near 46%. A family-wise analysis of the sex pheromone of this population confirmed that there were two distinct phenotypes regarding the E ratio. An '? 46% E strain' inhabits southern parts of Japan, in addition to an '? 38 % E strain,' which seems to be predominant in other regions of Japan.
Ruthenium-catalysed domino hydroformylation-hydrogenation-esterification of olefins

A novel catalytic domino reductive hydroformylation-esterification of olefins is reported. The optimal protocol makes use of an inexpensive Ru carbonyl catalyst and uses acetic acid as both solvent and reactant. In general, moderate to good yields are obtained using aliphatic or aromatic olefins including industrially relevant di-isobutene. This atom-efficient catalytic transformation provides straightforward access to various acetate esters from unfunctionalized olefins.

The rearrangements of 1-octyl, 1-decyl and 1-tridecyl intermediates obtained from thermal lead(IV) acetate (LTA) decarboxylation of nonanoic, undecanoic and tetradecanoic acid were investigated experimentally through analysis and distribution of the products. The relationships between 1,5-, 1,6- and possibly existing 1,7-homolytic hydrogen transfer in 1-octyl-radical, as well as successive 1,2-hydride shift in corresponding cation have been computed via Monte-Carlo method. Taking into account that ratios of 1,5-/1,6-homolytic rearrangements in 1-octyl- and 1-tridecyl radical are approximately the same, the simulation shows very low involvement of 1,7-hydrogen rearrangement (1,5-/1,6-/1,7-hydrogen rearrangement = 85:31:1) in 1-octyl radical.

BF3 etherate-induced formation of C7-C 16-alkyl D-glucopyranosides is used as the key step in their synthesis from glucose and C7-C16-alkanols.
Reptilian chemistry: volatile compounds from paracloacal glands of the American crocodile (Crocodylus acutus).

The secretion of the paracloacal glands of the American crocodile (Crocodylus acutus) contains over 80 lipophilic compounds, including saturated and unsaturated long-chain alcohols along with their formic, acetic, and butyric acid esters, and several isoprenoids. Most of these compounds were identified on the basis of mass spectra, obtained by GC-MS. In addition, identification of the major components was supported by infrared spectra obtained by GC-FTIR. Major differences are indicated in the composition of the paracloacal gland secretion of C. acutus and that of another crocodylid, the African dwarf crocodile (Osteolaemus tetraspis).
Cross-Coupling between Functionalized Alkylcopper Reagents and Functionalyzed Alkyl Halides
Tucker, Charles E.,Knochel, Paul
, p. 4781 - 4782 (2007/10/02)
Functionalized dialkylzincs treated with Me2Cu(CN)(MgCl)2 in DMPU undergo highly chemoselective cross-coupling reactions with functionalized alkyl iodides or benzylic bromides providing polyfunctional products in good to excellent yields.
