The asymmetric Michael reaction of 3(2H) furanones and alpha, beta-unsaturated ketones was investigated, with the employment of a bulky chiral primary amine. The protocol afforded a series of substituted furanone derivatives in a highly diastereo-(> 30 : 1 dr) and enantioselective (up to 93% ee) manner with generally good to excellent yields (up to 99%).

It is reported that cheap and easily available Hg(OTf)(2) can efficiently mediate the Sakurai-Hosomi reaction of N-tert-butyloxycarbonyl (Boc) amino sulfones, aldehydes, and alpha-fluoroalkyl ketones using allyltrimethylsilane, with the catalyst loading down to 0.5-5.0 mol%, enabling the facile access to synthetically valuable homoallylic alcohols or amines, respectively. A chemoselective 1,4-allylation of alpha,beta-unsaturated enones is also achieved under the catalysis of 5.0 mol% Hg(OTf)(2). In most cases, Hg(OTf)(2) exhibited intriguing properties superior to those of commonly used metal Lewis acids for such reactions, suggesting that mercury catalysis is worthwhile to explore.

A group of novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)bencene and 5-aryltriaz- 1-en-1-yl-1-phenyl-1H-pyrazole-4-carbonitrile derivatives have been successfully synthesized and characterized by spectroscopic analyses. The triazenes were obtained in moderate yield by a coupling reaction between 5-aminopyrazol-4-carbonitrile and aryl diazonium chlorides, and their structures were confirmed by detecting the CN functional group in both IR and C-13 NMR spectra. Conversely, the novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)benzene derivatives were obtained using a previously unreported and facile pathway starting with p-phenylenediamine with selected triethyl orthoalkylates and then hydrazine monohydrate, followed by refluxing in triethyl orthoalkylates. The structure of the methyl derivative was confirmed by X-ray analysis. The synthesized compounds were tested and evaluated as antimicrobial agents.

A general intermolecular anti-Michael reductive Heck reaction of alpha,beta-unsaturated esters with organobromides has been developed. Most topical classes of aryl, heteroaryl, and vinyl bromides were found to efficiently react with a variety of internal conjugated alkenes. This protocol set up a platform toward diverse alpha-arylated 1,6-dicarbonyl frameworks found in natural products and drugs, which are still highly challenging targets in traditional alpha-arylation protocols because of competitive selectivity of enolation. A removable directing group, gram-scale reaction, and modification of complex molecules have additionally demonstrated that the anti-Michael reductive Heck reaction is a powerful complementary strategy to the classical alpha-arylation approaches. Preliminary mechanistic studies are consistent with our proposed mechanistic design.

Alzheimer’s disease is a degenerative brain condition that is the leading cause of dementia affecting millions of people around the world. Therapeutic development has focused on the problem of the loss of basal forebrain cholinergic function, as it is the only evidence responsible for brain neurodegeneration in patients with Alzheimer’s disease. Several attempts to improve cholinergic neurotransmission have been investigated by minimizing synaptic degradation of acetylcholine using acetylcholinesterase inhibitors. In the current study, we explore the designing of a new series of nicotinonitrile-coumarin hybrids as potential acetylcholinesterase inhibitors. The new hybrids were prepared utilizing pyridine-2(1H)-thiones as starting precursors. The in vitro acetylcholinesterase (AChE) inhibitory activities were examined for the new nicotinonitrile-coumarin hybrid molecules, when compared with donepezil as a standard drug with IC(50)of 14 nM. Coumarin derivative, linked to 6-(4-nitrophenyl)-4-phenylnicotinonitrile, showed more effective inhibitory activity than the reference donepezil with IC(50)of 13 nM. The free radical-scavenging capabilities against DPPH of the new hybrid derivatives were screened. Additionally, their in vitro cytotoxic activities have been tested against various eukaryotic cells. Furthermore, docking study showed excellent interaction between nicotinonitrile-coumarin hybrids and AChE. [GRAPHICS] .

The reactivity of iodine(III) reagents towards nucleophiles is often associated with umpolung and cationic mechanisms. Herein, we report a general process converting a range of ketone derivatives into alpha-cyclopropanated ketones by oxidative umpolung. Mechanistic investigation and careful characterization of side products revealed that the reaction follows an unexpected pathway and suggests the intermediacy of non-classical carbocations.

In this work, we describe the development of the rearrangement for 7-aryl-substituted oxazolo[S,4-b]pyridines treated with aluminum chloride into synthetically hard-to-reach benzo[c][1,7]naphthyridinones. The discovered rearrangement is applied to a variety of electron-rich (hetero)arene substrates. It offers the advantages of mild conditions (90 degrees C temperature), fast reaction rates (<4 h), compatibility with air moisture, and the use of inexpensive commercial reagents. The proposed reaction mechanism and key elementary reaction acts were studied in detail using quantum chemical calculations. The photophysical properties of the synthesized compounds were studied by steady-state UV-vis spectroscopy. Name: 1,1,1-Triethoxyethane.

In spite of the fact that a variety of reactions have been exploited for creation of innumerable porous organic polymers (POPs), aldol condensation reactions between aldehydes and ketones leading to enones remain unutilized quite inexplicably. We surmised that the enone functionality can be exploited for stabilization of Pd akin to the manner of Pd(0) in Pd-2(dba)(3) by developing POPs based on aldol condensation reactions of polycarbonyl compounds with dialdehydes, and that such materials can be employed for catalytic transformations. By subjecting rationally designed tri-/tetraacetyl-functionalized aryl amines to aldol condensations with terephthalaldehyde, three different POPs, i.e., TPAPOPs 1-3, that feature enone functionalities have been synthesized and shown to exhibit palpable gas sorption properties. Remarkably, inverse uptake for sorption of H-2 over N-2 was observed for all POPs. As surmised, the representative POP, i.e., TPAPOP-1, was found to stabilize in situ-generated Pd(0) nanoparticles to enable application of the resultant material, i.e., Pd@TPAPOP-1, as a recyclable heterogeneous catalyst for a number of organic transformations. It is shown that coupling reactions such as Suzuki and Heck, and reductions such as nitro-to-amine and hydrogenation of olefins can be accomplished in a facile manner by employing Pd@TPAPOP-1 as a heterogeneous recyclable catalyst; the aforementioned transformations have been demonstrated on a broad set of substrates for each type.
