The first highly stereoselective organocatalytic intermolecular allylic alkylation of allylic alcohols with 1,3-dicarbonyls has been developed to allow the first...

Hydrogenation of alkyl and aryl ketones using H2 is catalytically achieved in 18 examples using 5 mol % B­(C6F5)3 in an ethereal solvent. In these cases the borane and ether...

An intramolecular rhodium-catalyzed transannulation of readily available cyanothiadiazoles containing an ester, amide, or ether as a linker is described. It provides a wide...

Various cryptands based on 1,3-dioxane decorated 1,3,5-trisubstituted-benzene building blocks, connected by different chains (exhibiting ester, ether, or triazol groups) to...

Vapour Pressure (P) and Enthalpy of Vaporisation (ΔHvap) of Raspberry Ketone and Eight Analogs at 298.15 K.

The effects of the CF2H moiety on H-bond (HB) acidity and lipophilicity of various compounds, when attached directly to an aromatic ring or to other functions like alkyls,...

An efficient, flexible, and stereoselective convergent route for constructing the trans-10-hydroxy-1,1-dimethyloctahydrodibenzo[a,d]cyclohepten-7-ones (5a−c) was achieved via...

A borocyclopropanation of (E)- and (Z)-allylic ethers and styrene derivatives via the Simmons–Smith reaction using a novel boromethylzinc carbenoid is described. The carbenoid...

Human adipose samples collected in Tokyo, Japan in 1970 and 2000 were analyzed for the presence of polybrominated dibenzo-p-dioxins (PBDDs), dibenzofurans (PBDFs), and diphenyl...

Antoine Equation Parameters Determined by Non-Linear Regression Analysis of the Vapour Pressure Data and Their Validity Range.

The gold­(I)-induced rearrangements of a variety of propargyl derivatives (ethers, acetals, acetates, and carbonates) were explored in the gas phase with experiments in an...

A stereoselective halo-etherification of chiral enamides is described here. This work provides an approach to halogen containing cyclic ethers and reveals further mechanistic...

Upon treatment with BF3·Et2O at low temperature, enantiopure benzyl-type ethers of arylglycidols with electron withdrawing substituents at the skeletal aryl group and electron...

Diisopropylsilyl bis-enol ethers are shown to be powerful intermediates for the diastereoselective dimerization and cross-coupling of cyclic ketones. The trends observed for the...

The alkali-metal silyl [K­(L)­SiPh3] (1; L = 18-crown-6 ether) catalyzed the hydrosilylation of activated CC double bonds. Isolation and characterization of an addition product...

Chloro-substituted triethylsilyl enol ethers derived from cyclo­hexanone and related ketones are converted with aluminum powder in the presence of indium trichloride to...

DABCO-mediated [4 + 4] domino annulation reactions of ynones and α-cyano-α,β-unsaturated ketones were discovered. The domino process affords an alternative route to...

Cyclic mixed acetals with pendant diazoketone side chains undergo efficient rearrangement to ether-bridged cyclooctanoid systems upon treatment with Cu(hfacac)2. This result...

Diisopropylsilyl bis-enol ethers are shown to be powerful intermediates for the diastereoselective dimerization and cross-coupling of cyclic ketones. The trends observed for the...

A novel γ-selective conjugate addition of 1-silyl-substituted dienol ethers to nitroalkenes activated by Lewis acids has been developed. The resulting α,β-unsaturated...
