Use of solid-phase microextraction to detect semiochemicals in synthetic and biological samples
… if a known semiochemical, 2-methyl-but-2-enal (2M2B), produced in commercial dog collars and behavioral adjustments sprays could be detected via SPME followed by gas chromatography-mass spectrometry (GC-MS) analysis. Collar pieces were placed in glass jars while the SPME fibers …

Nickel-catalyzed coupling reactions and synthetic studies toward ent-dioxepandehydrothyrsiferol via an epoxide-opening cascade
… could be obtained from a mixture of nickel, a,?-enal, and a silyl triflate. Under appropriate conditions [beta]-hydride elimination could occur to provide an allylic alcohol product. The nickel(0) catalyst could be regenerated in the presence of a base. Ethylene and terminal alkenes are …

Applications of Green Chemistry in Asymmetric Transfer Hydrogenation and Chiral Separations
… 1,3-hydrogen shift isomerization through an enal intermediate prior to transfer hydrogenation. Reaction conditions were optimized using chiral ruthenium complexes.</p> <p>The thermodynamic characteristics of the enantioseparation of the chiral benzyl alcohols under ACN-free RP-HPLC were also …

Pushing the limits of aldoxime dehydratases for the synthesis of industrial relevant nitriles and their use in chemo- and biocatalytic cascade reactions
… and a reduction of the produced 3-phenylprop-2-enal using an ene-reductase in a three step one-pot cascade in a co-factor neutral reaction. Screenings for an alcohol dehydrogenase and a suitable ene-reductase showed that the thermostable alcohol dehydrogenase BstADH and the enereductase Gox8 are …

Effects of Bran Content, Thermal Treatment, and Storage on Flavor Development and Functionality in Intermediate Wheatgrass Flour
… identified odor active VOACs included alkyl and enal aldehydes, alcohols, and furans, which are products of lipid oxidation. By the end of storage, whole IWG flour showed significantly greater intensity of nearly all identified VOACs, such as pentanal, hexanal, 1-octen-3-ol, and 2-pentylfuran, in …

I. Progress Toward Leiodelide A II. Palladium-Catalyzed Reactions of Enol Ethers
<p>Leiodermatium, a deep-water marine sponge, was collected by Fenical and co-workers off the coast of Palau as reported in 2006. Leiodelide A, a 19-membered ring macrolide which showed increased cytotoxicity when screened against HL-60 leukemia and OVAR-3 ovarian cancer cell lines, was isolated …
