Selective conversion of enol ethers into alcohols in the presence of alkenes using Hg(OAc)2-NaBH4

Alkyl enol ethers derived from aldehydes undergo selective oxymercuration-demercuration with aqueous Hg(OAc)2-NaBH4 in the presence of an alkene in good to excellent yield. This method allows the survival of mono-, trans and cis di-, and tri-substituted alkenes as well as cyclic alkenes.

Synthesis of (Z)-6-heneicosen-11-one, (+/-)(Z)-14-methyl-8-hexadecen-1-ol and (+/-)-5,6-dehydrosenedigitalene

Three naturally occurring compounds (Z)-6-heneicosen-11-one (1), (+/-)-(Z)-14-methyl-8-hexadecen-1-ol (2) and (+/-)-5,6-dehydrosenedigitalene (3) have been synthesised using lithium tetrachlorocuperate catalysed coupling reaction.

INSECT PHEROMONES AND THEIR ANALOGUES XXXI. SYNTHESIS OF DEC-5Z-EN-1-YL ACETATE AND HENEICOS-6Z-EN-11-ONE FROM A FUNCTIONALLY DIFFERENTIATED PRODUCT OF THE OZONOLYSIS OF CYCLOPENTENE

Dec-5Z-en-1-yl acetate and heneicos-6Z-en-11-one - pheromones of insects of the genera Agrotis and Orgyia, respectively - have been synthesized from a product of the functionally differentiated ozonolysis of cyclopentene.

Leukotriene antagonists

Compounds having the formula: STR1 are antagonists of leukotrienes of C4, D4 and E4, the slow reacting substance of anaphylaxis. These compounds are useful as anti-asthmatic, anti-allergic, anti-inflammatory agents, and cytoprotective agents.

Enamine synthesis using the Horner-Wittig reaction. Part 2. New acyl anion equivalents derived from (aminomethyl)diphenylphosphine oxides

Using the Horner-Wittig reagents (1-morpholino-alkyl)diphenylphosphine oxides (1), aromatic as well as aliphatic α,β-unsaturated aldehydes can be converted into the morpholino enamines of their respective homologous phenyl, ethyl and styryl ketones.These enamines can be easily converted into the corresponding ketones by mild, acid-catalyzed hydrolysis.The usefulness of these phosphine oxides as acyl anion equivalents is further demonstrated by the synthesis of dihydrojasmone and of (Z)-6-henicosen-11-one.

Unsaturated eicosanoic acids

Unsaturated eicosanoic acids and derivatives thereof which inhibit the synthesis of SRS-A are useful for treating and preventing asthma and allergic responses caused by SRS-A as well as useful in inhibiting inflammation.
