Rearrangement reactions of cycloalkenyl phenol and naphthyl ethers and the acid-catalyzed cyclization of the resulting product were investigated. Claisen rearrangement afforded 2-substituted phenol and naphthol derivatives. Combined Claisen and Cope rearrangement resulted in the formation of 4-substituted phenol and naphthol derivatives. In the case of cycloocthylphenyl ether the consecutive Cl...

The aim in this study was first to explain, detail the conversion of diacetates over time into chlorinated monoacetates following ether cleavage with AcCl norcantharimide derivatives help NMR technique and second, verify theoretically computationally. Ether reactions N-methyl, N-benzyl, N-acetoxyethyl-substituted were performed Ac2O or presence H2SO4, mechanisms these elucidated detail. Accordi...

A series of fatty acid ester and ether derivatives have been chemically synthesised based on carbohydrate and non-carbohydrate polyhydroxylated scaffolds. The synthesised compounds, along with their corresponding fatty acid monoglyceride antimicrobials, were evaluated for antimicrobial activity against Staphylococcus aureus and Escherichia coli. Of the derivatives synthesised, several of the ca...

Oximes, its ether derivatives and the corresponding hydroxylamines rearrange to secondary amines when reacted with PhSiH3 B(C6F5)3 as catalyst. Computations suggest a reduction–rearrangement be slightly favored over Beckmann-type sequence.

Enzymes such as lipases and proteases have been used catalysts in nearly anhydrous organic solvents diisopropyl ether hexane to carry out stereospecific selective enzymatic resolutions of carboxylic acid derivatives 2-bromohexadecanoic acid, which may be for prevention treatment bone loss-related diseases β-phenyllactic has a role human metabolite.

Ether derivatives are versatile organic compounds and have been applied in various fields of academia the chemical industry. Therefore, it is highly desirable to create procedures for their manufacture that more efficient sustainable. Catalytic reductive etherification with carbonyl moiety such as ketones/ aldehydes carboxylic acid has recently recognized a possible tool among several technique...

A profile (chromatographic pattern) of the neutral and acidic metabolites present in cerebrospinal fluid from newborns and infants was obtained by gas-liquid chromatography. The metabolites are those extracted with ethyl acetate and diethyl ether. They are converted to trimethylsilyl ether derivatives, and chromatographed on a column containing 5% silicone OV-101 (methyl) packed on Chromosorb W...
