摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.

标 题 :Synthesis of isoprenoid 1,5-dienes
发明人：KATZENELLENBOGEN JOHN A
权利人:UNIV ILLINOIS
摘要:Aliphatic acids containing an isoprenoid 1,5-diene moiety are prepared in high yields by the selective gamma alkylation of α,β-unsaturated acids with allylic electrophiles. The gamma-regioselectivity of the alkylation is controlled by the use of the dicopper(I) dienolates prepared from the α,β-unsaturated acids. The method offers a particularly facile means for synthesizing isoprenoid 1,5-diene natural products such as farnesoic acid by alkylation of senecioic acid with geranyl bromide; geranoic acid by alkylation of senecioic acid with 3,3-dimethallyl bromide; and dl-lanceol by alkylation of tiglic acid with an allylic bromide derived from dl-limonene. Such products find use in the synthesis of insect pheremones, insect juvenile hormones, and components of perfumes.

标 题:Synthesis of a low trans-content edible oil, non-edible oil, or fatty acid in a solid polymer electrolyte reactor

摘要:An electrochemical process for hydrogenating an unsaturated fatty acid, mixtures of two or more fatty acids, or the unsaturated fatty acid constituents of an edible or non-edible oil's triglycerides is performed using a solid polymer electrolyte reactor. Membrane electrode assemblies consist of a cation exchange membrane onto which porous anode and cathode electrodes are attached. As the electrodes are permeable, reactant and products enter and leave the membrane/cathode and membrane/anode reaction zones via the back sides of the electrodes. Hydrogen is generated in situ by the electro-reduction of protons that are formed at the anode and which migrate through the ion exchange membrane for reaction with the fifty acids or fatty acid constituents. In the disclosed process, only protons (H + ions) carry the current between the anode and the cathode. The need for a supporting electrolyte to conduct electricity has been circumvented. The disclosed process operates at a low to moderate temperature at atmospheric or moderate pressure without the use of a supporting electrolyte that will contaminate the oil. A novel partially hydrogenated oil product selected from the group consisting of a partially hydrogenated fatty acid, a partially hydrogenated triglyceride, and mixtures thereof is produced by the disclosed process. The product produced from the disclosed process has: a trans-isomer content lower than that of a similarly hydrogenated oil product formed in a high temperature chemical catalytic reaction process; a peroxide value of less than about 1.5%; free fatty acid content of less than about 0.02%; and, improved purity.
