Room-temperature palladium-catalyzed coupling of heteroaryl amines with aryl or heteroaryl bromides

Heteroaryl amines readily undergo Buchwald-Hartwig amination reactions with a range of aryl and heteroaryl bromides at room temperature using t-BuXPhos Pd-precatalyst and NaOt-Bu. The pharmaceutically attractive biaryl amines are generally formed in short reaction times (0.5-16 h) and in good to excellent yields. Georg Thieme Verlag Stuttgart – New York.

3-(alphaR)-alpha-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl) -3-hydroxybenzyl)-N-alkyl-N-arylbenzamides: Potent, non-peptidic agonists of both the mu and delta opioid receptors

Opioid analgesics with both mu and delta opioid receptor activation represent a new approach to the treatment of severe pain with an improved safety profile. Compounds with this profile may exhibit strong analgesic properties due to mu agonism, with a reduced side effect profile resulting from delta agonism. Replacing the p-diethylamide of the known potent delta opioid receptor selective agonist BW373U86 with a m-diethylamide resulted in a compound with agonist activity at both the mu and delta opioid receptors. Modifying the amide to an N-methyl-N-phenylamide increased agonist potency at both receptors. A series of 3-(alphaR)-alpha((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl) -3-hydroxybenzyl)-N-alkyl-N-arylbenzamides have been made to explore the structure-activity relationship (SAR) around the N-methyl-N-phenylamide. Several potent agonists of both the mu and delta opioid receptors have been identified, including (+)-3-((alphaR)-alpha ((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3- hydroxybenzyl)-N-(4-flourophenyl)-N-methylbenzamide (23), which has EC50 values of 0.67 and 1.1 nM at the mu (guinea pig ileum assay) and delta (mouse vas deferens assay) opioid receptors, respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Isoxazoles, you can also check out more blogs about33282-15-4

Isoquinolinylpyrazoles and pyridylisoxazoles as luminescent materials with sensorial ability towards pollutant toxic metal ions. Experimental and computational studies

The crystal structure and photoluminescence behaviour of two series of azole-based derivatives have been investigated. In the solid state, the compounds form head-to-tail dimers through intermolecular hydrogen bonds and emit bluish light in the range of 340?500 nm. The geometry parameters have been optimised by DFT calculations to analyse the molecular electrostatic potential (MEP) and the charge distribution in order to find the favourable molecular sites for metal interactions. The electronic properties of the frontier orbitals and their energy levels have been also measured. The compounds behave as fluorescent materials in solution and they exhibit sensorial abilities towards Hg2+, Pd2+, Pt4+, Cu2+, Zn2+ and Cd2+ metal ions. The ion sensing properties that the azoles present upon complexation have been followed by spectrophotometric and spectrofluorimetric titrations. Additionally, the stability constants of the complexes formed as well as the detection and quantification limits have been calculated. The best results are obtained for the detection of Zn2+ at concentration lower than 0.3 muM.

Palladium-catalyzed site-selective direct olefination of 6-electron-withdrawing group substituted 3-arylbenzo[: D] isoxazoles

A palladium-catalyzed direct olefination of 6-electron-withdrawing group substituted 3-arylbenzo[d]isoxazoles has been developed with exclusive site-selectivity and excellent E-stereoselectivity. It was found that the olefination occurred at the acidic C-7 position only, overriding a potential directing-group assisted bias. With the wide range of alkene patterns, the protocol allows convenient access to multifarious C-7 olefinated benzo[d]isoxazoles in moderate to good yields.

Comprehensive Study of the Organic-Solvent-Free CDI-Mediated Acylation of Various Nucleophiles by Mechanochemistry

Acylation reactions are ubiquitous in the synthesis of natural products and biologically active compounds. Unfortunately, these reactions often require the use of large quantities of volatile and/or toxic solvents, either for the reaction, purification or isolation of the products. Herein we describe and discuss the possibility of completely eliminating the use of organic solvents for the synthesis, purification and isolation of products resulting from the acylation of amines and other nucleophiles. Thus, utilisation of N,N?-carbonyldiimidazole (CDI) allows efficient coupling between carboxylic acids and various nucleophiles under solvent-free mechanical agitation, and water-assisted grinding enables both the purification and isolation of pure products. Critical parameters such as the physical state and water solubility of the products, milling material, type of agitation (vibratory or planetary) as well as contamination from wear are analysed and discussed. In addition, original organic-solvent-free conditions are proposed to overcome the limitations of this approach. The calculations of various green metrics are included, highlighting the particularly low environmental impact of this strategy.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 42831-50-5
