Thermochemical properties and regularities of amides, anilides, and amidic acids

open access: yesActa Chimica Slovenica, 2018
The thermodynamic properties of carbamide and its alkyl substituted were studied insufficiently. In this article, the enthalpies of combustion of ΔсН of some amides, anilides and amidic acids have been determined experimentally; their standard enthalpies

Targeted Derepression of the Human Immunodeficiency Virus Type 1 Long Terminal Repeat by Pyrrole-Imidazole Polyamides [PDF]

open access: yes, 2002
The host factor LSF represses the human immunodeficiency virus type 1 long terminal repeat (LTR) by mediating recruitment of histone deacetylase. We show that pyrrole-imidazole polyamides targeted to the LTR can specifically block LSF binding both in ...

2-({5-[(4-Chlorophenoxy)methyl]-4-phenyl-4H-1,2,4-triazol-3-yl}sulfanyl)-N-phenylacetamide

open access: yesIUCrData, 2016
The title molecule, C23H19ClN4O2S, is in an `extended' conformation. In the crystal, pairwise N—H...N and C—H...O hydrogen bonds lead to the formation of `stair-step' chains.

Raman spectroscopy and determination of soil yeasts

open access: yesZaštita Materijala, 2016
In this paper, two isolates of yeasts, members of the genus Candida, have been examined using Raman spectroscopy. The yeasts were isolated from soils sampled at the town park in Tivat (Montenegro) and experimental farm Radmilovac (Serbia), by the ...

Analysis of cholic acid amides by high-performance liquid chromatography

open access: yesZaporožskij Medicinskij Žurnal, 2012
The method of preparative purification of the obtained amides of cholic acid by HPLC was developed. The structure of the compounds was confirmed by 1H NMR spectroscopy and mass spectrometry. Purity of compounds was confi rmed by chromatography.

Generation of Mixed Anhydrides via Oxidative Fragmentation of Tertiary Cyclopropanols with Phenyliodine(III) Dicarboxylates

open access: yesMolecules, 2020
Oxidative fragmentation of tertiary cyclopropanols with phenyliodine(III) dicarboxylates in aprotic solvents (dichloromethane, chloroform, toluene) produces mixed anhydrides. The fragmentation reaction is especially facile with phenyliodine(III) reagents

Benzylation of N-phenyl-2-phenylacetamide under microwave irradiation [PDF]

open access: yesJournal of the Serbian Chemical Society, 2008
N-Phenyl-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide under microwave irradiation in a solvent-free system. The reactions were also performed in the presence of phase-transfer catalysts.

Selective C-N σ Bond Cleavage in Azetidinyl Amides under Transition Metal-Free Conditions

open access: yesMolecules, 2019
Functionalization of amide bond via the cleavage of a non-carbonyl, C-N σ bond remains under-investigated. In this work, a transition-metal-free single-electron transfer reaction has been developed for the C-N σ bond cleavage of N ...
