Aza-heterocyclic frameworks through intramolecular pi-system trapping of spiro-N-acyliminiums generated from isoindolinone

Spiro-acetoxylactams as key substrates were obtained straightforwardly by the tandem regioselective reduction/O-acylation of spiro-isoindolinone-imides. The latter were produced in large scale in three steps from homophthalic acid. These imides were useful to provide in one step isoindolinones bearing hydroxymethyl-amide functions, tethered at quaternary carbon centre with promising biological issues. Submitted to Bronsted (TFA neat) and Lewis acid (trimethylsilyltrifluoro-methanesulfonic (TMSOTf) 10 mol%), the spiro-acetoxylactams undergo pi-cyclization of spiro-N-acyliminiums to provide diastereoselectively with pi-aromatic original pyrrolopyrido- and pyrroloazepino-isoindoles fused or not to aromatic systems. With pi-olefins, pyrrolopyridines and pyrrolo-azepines fused to isoindoline or containing amino-acids were isolated. A reaction mechanism producing all these systems is also discussed.

A high yield method for the direct amidation of long-chain fatty acids

The amidation of long-chain fatty acids is the key step for preparing surfactants with excellent interfacial activity. Gas chromatography-mass spectrometry was employed to detect the reactants and products in the direct amidation reactions. The conversion and the concentration of the amides in the reaction process were also investigated to determine the best catalyst, the reaction rate constants, and activation energy. It was identified that the amidation reaction of the long-chain phenyl fatty acid was a zero-order reaction and 3,4,5-trifluorophenylboronic acid was the most effective catalyst by which the activation energy reduced to 55.79 kJ/mol from 95.44 kJ/mol. The method can be applied to other long-chain fatty acids, saturated or unsatureated. The turning-over-temperature was 156 degrees C, over which high yields can be achieved without any catalyst. These provide a reference for the preparation of long-chain fatty acid amides.

Thermodynamic Description of Synergy in Solvent Extraction: II Thermodynamic Balance of Driving Forces Implied in Synergistic Extraction

In the second part of this study, we analyze the free energy of transfer in the case of synergistic solvent extraction. This free energy of the transfer of an ion in dynamic equilibrium between two coexisting phases is decomposed into four driving forces combining long-range interactions with the classical complexation free energy associated with the nearest neighbors. We demonstrate how the organometallic complexation is counterbalanced by the cost in free energy related to structural change on the colloidal scale in the solvent phase. These molecular lormulan forces of synergistic extraction are driven not only by the entropic term associated with the tight packing of electrolytes in the solvent and by the free energy cost of coextracting water toward the hydrophilic core of the reverse aggregates present but 1 also by the entropic costs in the formation of the reverse aggregate and by the interfacial bending energy of the extractant molecules packed around the extracted species. Considering the sum of the terms, we can rationalize the synergy observed, which cannot be explained by classical extraction modeling. We show an industrial synergistic mixture combining an amide and a phosphate complexing site, where the most efficient/selective mixture is observed for a minimal bending energy and maximal complexation energy.

Synthesis of N-Acyl Sulfamates from Fluorosulfonates and Potassium Trimethylsilyloxyl Imidates

An efficient and operationally simple method for the synthesis of N-acyl sulfamates from fluorosulfonates and potassium trimethylsilyloxyl imidates as amide precursor is reported. This approach showed broad substrate scope, mild and base-free reaction conditions, short reaction time, and high to excellent yields. Notably, we demonstrated the power of this reaction in the rapid late-stage functionalization of three complex phenol-containing bioactive molecules. Given the prevalence of phenol-containing drugs and building blocks, this method is applicable toward a diversity-oriented drug discovery.

Variously substituted 2-oxopyridine derivatives: Extending the structure-activity relationships for allosteric modulation of the cannabinoid CB2 receptor

We previously reported the 2-oxopyridine-3-carboxamide derivative EC21a as the first small synthetic CB2R positive allosteric modulator which displayed antinociceptive activity in vivo in an experimental mouse model of neuropathic pain. Herein, we extended the structure-activity relationships of EC21a through structural modifications regarding the p-fluoro benzyl moiety at position 1 and the amide group in position 3 of the central core. The characterization in vitro was assessed through radioligand binding experiments and functional assays (GTP gamma S, cAMP, beta arrestin2). Among the new compounds, the derivatives Al (SV-10a) and A5 (SB-13a) characterized respectively by fluorine atom or by chlorine atom in ortho position of the benzylic group at position 1 and by a cycloheptane-carboxamide at position 3 of the central core, showed positive allosteric behavior on CB2R. They enhanced the efficacy of CP55,940 in [S-35]GTP gamma S assay, and modulated CP55,940-dependent beta arrestin2 recruitment and cAMP inhibition. The obtained results extend our knowledge of the structural requirements for interaction with the allosteric site of CB2R. (C) 2020 Elsevier Masson SAS. All rights reserved.
