N-Heterocyclic carbene-catalyzed deaminative cross-coupling of aldehydes with Katritzky pyridinium salts

By employing an N-heterocyclic carbene (NHC) catalyst, we developed a versatile catalytic system that enables deaminative cross-coupling reactions of aldehydes with redox-active pyridinium salts. Katritzky pyridinium salts behave as single-electron oxidants capable of generating alkyl radicals enabled by the redox properties of the enolate form of Breslow intermediates. The resultant alkyl radical undergoes efficient recombination with the NHC-bound aldehyde-derived carbonyl carbon radical for the formation of a C-C bond. The mild and transition metal-free reaction conditions tolerate a broad range of functional groups, and its utility has been further demonstrated by the modification of a series of peptide feedstocks and application to the three-component dicarbofunctionalization of olefins.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4265-16-1, and how the biochemistry of the body works.4265-16-1

Ultrasound mediated, green innovation for the synthesis of polysubstituted 1,4-dihydropyridines

An elegant, atom efficient protocol via a one-pot four-component cyclocondensation reaction of aromatic aldehydes, malononitrile, acetylenedicarboxylates and arylamines catalyzed by copper(I) iodide in aqueous medium under ultrasound irradiation has been developed for the synthesis of a series of novel pharmacologically interesting polysubstituted 1,4-dihydropyridines. In comparison with the reported methods, our approach is expedient and offers several advantages such as: a shorter reaction time, excellent yields, milder conditions, convenience and environmental benignity. We have herein successfully demonstrated the utility of sonication in a multicomponent reaction (MCR), which exhibits a better functional group tolerance, and straightforward product isolation and purification by precipitation.

Synthesis and catalytic activity of ruthenium indenylidene complexes bearing unsymmetrical NHC containing a heteroaromatic moiety

New robust and air stable ruthenium(ii) indenylidene second generation olefin metathesis catalysts with unsymmetrical N-heterocyclic carbene (NHC) ligands were synthesized. Model metathesis reactions were performed in the presence of newly-developed complexes in commercial grade toluene under air, leading to high conversions and good selectivities.

Aminoguanidine hydrazone derivatives as non-peptide NPFF1 receptor antagonists reverse opioid induced hyperalgesia

Neuropeptide FF receptors (NPFF1R and NPFF2R) and their endogenous ligand Neuropeptide FF have been shown previously to display anti-opioid properties and to play a critical role in the adverse effects associated with chronic administrations of opiates including the development of opioid-induced hyperalgesia and analgesic tolerance. In this work, we sought to identify novel NPFF receptors ligands by focusing our interest on a series of heterocycles as rigidified non-peptide NPFF receptor ligands, starting from already described aminoguanidine hydrazones (AGH’s). Binding experiments and functional assays highlighted AGH 1n and its rigidified analog 2-amino-dihydropyrimidine 22e for in vivo experiments. As earlier shown with the prototypical dipeptide antagonist RF9, both 1n and 22e reduced significantly the long lasting fentanyl-induced hyperalgesia in rodents. Altogether these data indicate that AGH rigidification maintains nanomolar affinities for both NPFF receptors, while improving antagonist character towards NPFF1R.
