Benzene-di-N-substituted carbamates as conformationally constrained substrate analogs of cholesterol esterase [PDF]

, 2014
Benzene-1,2-, 1,3-, and 1,4-di-N-substituted carbamates (1-15) are synthesized as the constrained analogs of gauche, eclipsed, and anti conformations, respectively, for the glycerol backbones of triacylglycerol.

Pollution des eaux de surface par les carbamates

, 2010
Les carbamates, pesticides organiques dérivés de l'acide carbamique, constituent le premier groupe chimique en utilisation et en diversité : leur large spectre d'action (insecticide, herbicide, fongicide) ainsi que leur faible persistance dans l ...

Resveratrol-Based Carbamates as Selective Butyrylcholinesterase Inhibitors: Design, Synthesis, Computational Study and Biometal Complexation Capability

Molecules
Considering our previous experience in the design of new cholinesterase inhibitors, especially resveratrol analogs, in this research, the basic stilbene skeleton was used as a structural unit for new carbamates designed as potentially highly selective ...

Proline-Based Carbamates as Cholinesterase Inhibitors

Molecules, 2017
Series of twenty-five benzyl (2S)-2-(arylcarbamoyl)pyrrolidine-1-carboxylates was prepared and completely characterized. All the compounds were tested for their in vitro ability to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), and

Synthesis, Characterization, And Self-Assembly Of Bi-Carbamates And Tri-Carbamates

, 2012
Recent decades have witnessed the discovery of a wide variety of nanomaterials. These nanomaterials vary from zero-dimensional nanodots to three-dimensional nanoflowers. However the properties of these nanomaterials have not been fully explored.

Crystal structures of ethyl {2-[4-(4-isopropylphenyl)thiazol-2-yl]phenyl}carbamate and ethyl {2-[4-(3-nitrophenyl)thiazol-2-yl]phenyl}carbamate

Acta Crystallographica Section E: Crystallographic Communications, 2016
The title compounds, C21H22N2O2S (I) and C18H15N3O4S (II), are structural analogs of the alkaloid Thiosporine B. Both molecules adopt a near-planar V-shaped conformation, which is consolidated by intramolecular N—H...N and C—H...O hydrogen bonds.

Atropisomerism of Aromatic Carbamates

Chemistry – A European Journal, 2010
Abstractortho‐Haloarylcarbamates like 1–4 show a high rotational barrier about the Naryl bond of up to 91.6 kJ mol−1 as found for 1, which was determined by 2D exchange NMR spectroscopy (EXSY). It was further demonstrated that the height of the barrier not only depends on the substituents at the axis of chirality, but is also influenced by electronic ...

The chemistry of carbamates

, 2000
Carbamic acid, H2NCOOH, the half amide of carbonic acid, does not exist as the free acid. Only some heterocyclic carbamic acids form relatively stable compounds. In contrast to this, carbamates including derivatives resulting from replacement of hydrogen

Amidation through carbamates

, 2009
N-Alkyl carbamates of primary amines are easily converted into amides under treatment with Grignard reagents. Consequently, primary amines can be converted into amides in a one-pot reaction through carbamate protection and Grignard addition.
