An efficient tandem synthesis of alkyl aryl ethers, including valuable building blocks of dialdehyde and dinitro groups under microwave irradiation and solvent free conditions on potassium carbonate as a mild solid base has been developed. A series of alkyl aryl ethers were obtained from alcohols in excellent yields by following the Williamson ether synthesis protocol under practical mild condi...

3α,5α-Cyclocholestan-6β-yl alkyl and aryl ethers were proved to be efficient cholesteryl donors in the electrochemical synthesis of glycoconjugates. 3α,5α-Cyclocholestan-6β-ol (i-cholesterol) and its tert-butyldimethylsilyl ether can also be used for this purpose. The i-cholesterol derivatives show similar reactivities to those of previously studied 3α,5α-cyclocholestan-6β-thioethers.

By free radical addition of ethanedithiol to alkyl- and cycloalkyl-substituted methylene dioxolanes, the bis-adducts tested then as a plasticizer for PVC have been obtained. It has established result carried out investigations that introduction synthesized compounds into composition improves physical-mechanical properties, which connected with availability sulfur atoms, carbonyl groups ether bo...

N-Alkyl 2-pyridones and other enolizable heterocycles are important synthetic constructs, due to their prevalence in natural products and pharmaceutical targets and their capacity to serve as models for a number of biological and chemical processes. The disclosed Au(I)-catalyzed reaction utilizes 2-propargyloxypyridines to access N-alkylated 2-pyridone products derived from both 5-exo and 6-end...

BACKGROUND Binding of two 9-O-(ω-amino) alkyl ether berberine analogs BC1 and BC2 to the RNA triplex poly(U)(•)poly(A)(*)poly(U) was studied by various biophysical techniques. METHODOLOGY/PRINCIPAL FINDINGS Berberine analogs bind to the RNA triplex non-cooperatively. The affinity of binding was remarkably high by about 5 and 15 times, respectively, for BC1 and BC2 compared to berberine. The s...

The effect of temperature on the ether content of the glycerophospholipids of Tetrahymena pyriformis W was examined. The only ether detected was 1-O-hexadecyl glycerol (alpha-chimyl alcohol). The data provide evidence that the class 1-O-alkyl-2-acyl-sn-glycero-3-(2-aminoethyl)-phosphate (1-alkyl PsE), in addition to the previously reported 1-O-alkyl-2-acyl-sn-glycero-3-(2-aminoethyl)-phosphonat...
