Cross-coupling of triallyl(aryl)silanes with aryl bromides and chlorides: An alternative convenient biaryl synthesis

Cross-coupling of a diverse range of aryl bromides with triallyl(aryl)silanes is effective in the presence of PdCl2/PCy 3 and tetrabutylammonium fluoride (TBAF) in DMSO-H2O to give various biaryls in good yields. It is worthwhile to note that the all-carbon-substituted arylsilanes, stable towards moisture, acid, and base and easily accessible, serve as a highly practical alternative to their aryl(halo)silane counterparts. A catalyst system consisting of [eta3-C3H5)PdCl]2 and 2-[2,4,6-(i-Pr)3C6Ha]-C6H4PCy 2 and use of TBAF¡¤ 3 H2O in THF-H2O are effective especially for the cross-coupling with aryl chlorides. Both of the catalyst systems tolerate a broad spectrum of common functional groups. The high efficiency of reactions is presumably due to the ready cleavage of the allyl groups upon treatment with TBAF¡¤3 H2O and an appropriate amount of water. Diallyl(diphenyl)silane also cross-couples with various aryl bromides and chlorides in good yields, whereas allyl(triphenyl)silane gives the cross-coupled products in only moderate yields. Through sequential cross-coupling of bromochlorobenzenes with different arylsilanes, a range of unsymmetrical terphenyls are accessible in good overall yields.

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.

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.

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.
