Massah, Ahmad R. published the artcileSolvent-free Williamson synthesis. An efficient, simple, and convenient method for chemoselective etherification of phenols and bisphenols, Related Products of naphthyridine, the publication is Synthetic Communications (2007), 37(11), 1807-1815, database is CAplus.

Etherification of phenols with dimethyl- and diethylsulfates and benzyl chloride was performed efficiently in the presence of a suitable solid base, NaHCO₃ or K₂CO₃, under solvent-free conditions. The reaction proceeded rapidly at low temperature, and the corresponding ethers were obtained with high purity and excellent yield. Selective etherification of electron-poor phenols in the presence of electron-rich ones and also selective mono-etherification of bisphenols are the noteworthy advantages of this method. This method is environmentally friendly.

Morioku, Kumika published the artcileConcurrent Formation of Carbon-Carbon Bonds and Functionalized Graphene by Oxidative Carbon-Hydrogen Coupling Reaction, Safety of 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Scientific Reports (2016), 25824pp., database is CAplus and MEDLINE.

Oxidative C-H coupling reactions were conducted using graphene oxide (GO) as an oxidant. GO showed high selectivity compared with commonly used oxidants such as (diacetoxyiodo) benzene and 2,3-dichloro-5,6-dicyano-p-benzoquinone. A mechanistic study revealed that radical species contributed to the reaction. After the oxidative coupling reaction, GO was reduced to form a material that shows electron conductivity and high specific capacitance. Therefore, this system could concurrently achieve two important reactions: C-C bond formation via C-H transformation and production of functionalized graphene.

A wholly aromatic polyketone containing 2,2′-dimethoxy-1,1′-binaphthylylene moiety was successfully synthesized via electrophilic aromatic aroylation polycondensation with the aid of trifluoromethanesulfonic acid (TfOH) or phosphorus(V) oxide-methanesulfonic acid mixture (P₂O₅-MsOH). The polycondensation reactions employing two sets of monomers of opposite combination that should afford the same structure of repeating unit showed distinct results. The polycondensation employing 2,2′-dimethoxy-1,1′-binaphthyl (4) as the acyl-acceptant monomer proceeded to give medium-mol.-weight polymer. The polymer synthesis via transformation of biaryl 4 into the corresponding acyl-donor monomer 12 followed by polycondensation with 2,2′-dimethoxybiphenyl (1) predominated the procedure of direct usage of biaryl 4 as the acyl-acceptant monomer. Acyl-acceptant monomer has been demonstrated to play a more crucial role in determination of polymerizability than acyl-donor one.

Sancho, Raquel published the artcilePolyproline derivatives as chiral selectors in high performance liquid chromatography: Chromatographic and conformational studies, Formula: C22H18O2, the publication is Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences (2008), 875(1), 93-101, database is CAplus and MEDLINE.

A proline oligopeptide-derived chiral selector (CS), containing 3,5-dimethylphenylcarbamate residues on the 4 position of the pyrrolidine rings, was bonded to a silica gel chromatog. matrix by the N-terminal group. The chromatog. behavior of the resulting chiral stationary phase (CSP) was compared with that of a CSP containing the analogous monomeric CS and that resulting from bonding of the polyproline-derived CS by the carboxy-terminal group using several solvents as mobile phase. The CSs were also studied from the conformational point of view in solution using CD and ¹³C NMR. A relation was found between the presence of an ordered conformation in the particular conditions used and increased enantioselectivity.

Novell, Arnau published the artcileOctaproline, a conformationally flexible chiral selector in liquid chromatographic enantioseparation, Safety of 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Journal of Chromatography A (2014), 109-118, database is CAplus and MEDLINE.

A proline octapeptide-derived chiral selector (CS) end-capped using a pivaloyl group was covalently linked to a silica gel chromatog. matrix by the C-terminal group. The chromatog. behavior of the resulting chiral stationary phase (CSP) using different conditions was compared to those containing 3,5-dimethylphenylcarbamate residues on the proline units. An enantioseparation ability highly dependent on the mobile phase used is observed for these CSPs. When mixtures of alkane/alc. or alkane/ether were used as mobile phase a similar enantioselectivity was obtained. Nevertheless, in the presence of chlorinated solvents, and without a hydrogen bonding donor in the mobile phase, enantioselectivity is extremely reduced. The reversibility of this phenomenon, attributed to a conformational change in the CS, was examined

Novell, A. published the artcileMonolithic silica columns with covalently attached octaproline chiral selector. Dependence of performance on derivatization degree and comparison with a bead-based analogue, Synthetic Route of 2960-93-2, the publication is Journal of Chromatography A (2015), 124-132, database is CAplus and MEDLINE.

A monolithic silica gel chromatog. matrix was derivatized repetitively with an octaproline-derived chiral selector (CS). The increasingly derivatized column was tested after each derivatization reaction. The enantioseparation ability, resolution and efficiency were found to depend on the content of CS attained after each reaction. Moreover, enantioselectivity and performance of the column with the highest CS coverage were compared to those of a bead-based chiral stationary phase (CSP) counterpart. The octaproline-derivatized monolithic column demonstrated increased enantioseparation factors, resolution and broader applicability than the particle-based column. Finally, the loading capacity of the CSPs was also examined The monolithic octaproline-derived column permits the separation of 3-20 times higher molar amounts of the tested analytes (depending on the compound considered) than the particle-based counterpart. The enhanced capabilities of the derivatized monolithic column with respect to that of a bead-based counterpart cannot be explained only on the basis of an increased CS coverage. The involvement of an effect produced by the chromatog. silica support structure in the obtained results is discussed.

A straightforward synthesis of a sterically hindered and electron rich bidentate monophosphine biaryl ligand Sym-Phos (I) exhibiting C,P-type of complexation was realized in a high yield starting from simple substrates in easily affordable conditions. In combination with a palladium source, the obtained ligand formed a highly active catalyst mediating sterically demanding Suzuki-Miyaura coupling reactions in aqueous media even at 60 °C and with no need to protect the reaction mixture by an inert gas.
