Radical and Ionic Mechanisms in Rearrangements of o-Tolyl Aryl Ethers and Amines Initiated by the Grubbs–Stoltz Reagent, Et₃SiH/KO^tBu

Molecules, 2021
Rearrangements of o-tolyl aryl ethers, amines, and sulfides with the Grubbs–Stoltz reagent (Et3SiH + KOtBu) were recently announced, in which the ethers were converted to o-hydroxydiarylmethanes, while the (o-tol)(Ar)NH amines were transformed into ...

Ligand-Enabled, Copper-Promoted Regio- and Chemoselective Hydroxylation of Arenes, Aryl Halides, and Aryl Methyl Ethers.

Journal of Organic Chemistry, 2016
We report here a practical method for the ortho C-H hydroxylation of benzamides with inexpensive copper(II) acetate monohydrate and a pyridine ligand.

Isobaric Vapour Liquid Equilibrium at 101.3 kPa for the Binary Mixtures 2-Methyl-2-Butene / Methanol and Isopentane / Methanol

Chemical Engineering Transactions, 2013
Due to the increased interest for using tertiary ethers as fuel additives (such as TAME – tert-amyl-methyl-ether synthesis), the research intensified to study its thermodynamic aspects.

Direct and selective hydrogenolysis of arenols and aryl methyl ethers

Nature Communications, 2015
For valorization of biomass, the conversion of lignin to deoxygenated bulk aromatic compounds is an emerging subject of interest. Because aromatic rings are susceptible to metal-catalysed hydrogenation, the selective hydrogenolysis of carbon–oxygen bonds

Transition-metal-free formal cross-coupling of aryl methyl sulfoxides and alcohols via nucleophilic activation of C-S bond

Nature Communications, 2020
Cross-coupling processes without the use of transition metals are challenging to achieve. Here, the authors show a transition-metal-free cross-coupling utilizing aryl(heteroaryl) methyl sulfoxides and alcohols to afford alkyl aryl(heteroaryl) ethers and ...

Cyanovinylation of Aldehydes: Organocatalytic Multicomponent Synthesis of Conjugated Cyanomethyl Vinyl Ethers

Molecules, 2021
A novel organocatalytic multicomponent cyanovinylation of aldehydes was designed for the synthesis of conjugated cyanomethyl vinyl ethers. The reaction was implemented for the synthesis of a 3-substituted 3-(cyanomethoxy)acrylates, using aldehydes as ...

Bile acids. OV. 2,2-Dimethoxypropane: an esterifying agent preferred to diazomethane for chenodeoxycholic acid.

Journal of Lipid Research, 1978
Artifacts formed by methylation of chenodeoxycholic acid with diazomethane are identical to the synthetic 3alpha- and 7 alpha-monomethyl ethers of methyl chenodeoxycholate. The extent of formation of these artifacts with time has been studied.

Heterogeneous acidic catalysts for the tetrahydropyranylation of alcohols and phenols in green ethereal solvents

Beilstein Journal of Organic Chemistry, 2018
The application of heterogeneous catalysis and green solvents to the set up of widely employed reactions is a challenge in contemporary organic chemistry. We applied such an approach to the synthesis and further conversion of tetrahydropyranyl ethers, an

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

Molecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.
