Heterogeneous AlPO4(SO3H) nanosheets: novel catalyst for the multi-component synthesis of quinazolinones and highly functionalized piperidines

Nanosheets AlPO4(SO3H) as a highly active solid acid catalyst were prepared and characterized. The morphology of obtained catalyst exhibited nanosheets with similar to 25-35 nm thickness. The heterogeneous nanocatalyst was characterized by FT-IR, EDX, and FE-SEM analysis. The nanosulfonated-AlPO4 were found useful for cyclization synthesis of highly functionalized piperidines and quinazolinones derivatives in good to excellent yields. Notable features include easy and quick isolation of products, ease of handling of the catalyst at low cost, no need to purify with column chromatography, and mild reaction conditions. In addition, according to the literature, another significant feature of our method for quinazolinone synthesis is that structurally diverse molecules were synthesized. Finally, the newly developed catalytic systems avoid the use of toxic metal catalysts and were reused up to 5 times without a noticeable their catalytic activity.

A Route to 1-Deoxynojirimycin and 1-Deoxymannojirimycin Derivatives with Quaternary Centers Adjacent to the Ring Nitrogen from Methyl alpha-d-Mannopyranoside

6-Alkylated-8-azido-1,6-octadiene derivatives were prepared from methyl alpha-d-mannopyranoside. The sequence to allylic azide precursors included a Horner-Wadsworth-Emmons reaction with a concomitant epimerization that ultimately enabled synthesis of 1-deoxynojirimycin as well as 1-deoxymannojirimycin derivatives. Thermally promoted allylic acid rearrangement followed by triazoline formation, then decomposition to aziridine and finally reaction with acetic acid was used to generate products that have quaternary anomeric centers adjacent to the piperidine ring nitrogen atom (cyclic alpha-tertiary amines). The stereoselectivity is accounted for based on minimization of steric interactions in the transition state structure, favoring the product where the methyl substituent is equatorial and the vinyl group prefers to be axial.

ERG Responses in Mice with Deletion of the Synaptic Ribbon Component RIBEYE

PURPOSE. To determine the influence of RIBEYE deletion and the resulting absence of synaptic ribbons on retinal light signaling by electroretinography. METHODS. Full-field flash electroretinograms (ERGs) were recorded in RIBEYE knock-out (KO) and wild-type (WT) littermate mice under photopic and scotopic conditions, with oscillatory potentials (OPs) extracted by digital filtering. Flicker ERGs and ERGs following intravitreal injection of pharmacological agents were also obtained under scotopic conditions. RESULTS. The a-wave amplitudes were unchanged between RIBEYE KO and WT mice; however, the b-wave amplitudes were reduced in KOs under scotopic, but not photopic, conditions. Increasing stimulation frequency led to a greater reduction in RIBEYE KO b-wave amplitudes compared with WTs. Furthermore, we observed prominent, supernormal OPs in RIBEYE KO mice in comparison with WT mice. Following intravitreal injections with L-2 amino-4-phosphonobutyric acid and cis-2,3 piperidine dicarboxylic acid to block ON and OFF responses at photoreceptor synapses, OPs were completely abolished in both mice types, indicating a synaptic origin of the prominent OPs in the KOs. Conversely, tetrodotoxin treatment to block voltage-gated Na+ channels/spiking neurons did not differentially affect OPs in WT and KO mice. CONCLUSIONS. The decreased scotopic b-wave and decreased responses to increased stimulation frequencies are consistent with signaling malfunctions at photoreceptor and inner retinal ribbon synapses. Because phototransduction in the photoreceptor outer segments is unaffected in the KOs, their supernormal OPs presumably result from a dysfunction in retinal synapses. The relatively mild ERG phenotype in KO mice, particularly in the photopic range, is probably caused by compensatory mechanisms in retinal signaling pathways.

One-Step Synthesis of Aliphatic Potassium Acyltrifluoroborates (KATs) from Organocuprates

A one-step synthesis of aliphatic KATs from organocuprates is reported. Organolithium and organomagnesium reagents were readily transmetalated onto Cu(I) and coupled with a KAT-forming reagent to yield the respective aliphatic KAT. The protocol is suitable for primary, secondary and-for the first time-tertiary alkyl substrates. These protocols considerably expand the range of KATs that can be readily accessed in one step from commercially available starting materials.

Novel 2-cyanoacrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene derivatives as potent anticancer agents

Ethyl 2-acrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate as well as its correspondingbis-derivatives,5-10, with aliphatic linkers were synthesized, fully characterized, and tested as novel anticancer agents. The targeted compounds,5-10, were obtained by the Knoevenagel condensation reactions ofbis-o- or -p-aldehyde with a molar ratio of ethyl 2-(2-cyanoacetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate of2in the presence of piperidine in excellent yields (93-98%). The in vitro anticancer activities of the prepared compounds were evaluated against HepG2, MCF-7, HCT-116, and BJ1 cells. Compounds7and9emerged as the most promising compounds, with IC(50)values of 13.5 and 32.2 mu g/ml, respectively, against HepG2 cells, compared with the reference drug doxorubicin (IC50: 21.6 mu g/ml). Real-time reverse-transcription polymerase chain reaction was used to measure the changes in expression levels of the COL10A1 and COL11A1, ESR1, and ERBB2, or AXIN1 and CDKN2A genes within the treated cells, as genetic markers for colon, breast, or liver cancers, respectively. Treatment of the colon cancer cells with compounds5,9, and10, or breast and liver cancers cells with compounds7,8,9, and10downregulated the expression of the investigated tumor markers. The DNA damage values (depending on comet and DNA fragmentation assays) increased significantly upon treatment of colon cancer cells with compounds5,9, and10, and breast and liver cells with compounds8,9, and10. The structure-activity relationship suggested that the increase of the chain of the alkyl linker increases the anticancer activity and the compounds withbis-cyanoacrylamide moieties are more active than those with one cyanoacrylamide moiety.

Electrochemical Oxidation of Organic Molecules at Lower Overpotential: Accessing Broader Functional Group Compatibility with Electron-Proton Transfer Mediators

CONSPECTUS: Electrochemical organic oxidation reactions are highly appealing because protons are often effective terminal electron acceptors, thereby avoiding undesirable stoichiometric oxidants. These reactions are often plagued by high overpotentials, however, that greatly limit their utility. Single-electron transfer (SET) from organic molecules generates high-energy radicalcations. Formation of such intermediates often requires electrode potentials far above the thermodynamic potentials of the reaction and frequently causes decomposition and/or side reactions of ancillary functional groups. In this Account, we show how electrocatalytic electron-proton transfer mediators (EPTMs) address this challenge. EPTMs bypass the formation of radical-cation intermediates by supporting mechanisms that operate at electrode potentials much lower (>= 1 V) than those of analogous direct electrolysis reactions. The stable aminoxyl radical TEMPO (2,2,6,6-tetramethylpiperidine N-oxyl) is an effective mediator for electrochemical alcohol oxidation, and we have employed such processes for applications ranging from pharmaceutical synthesis to biomass conversion. A complementary electrochemical alcohol oxidation method employs a cooperative Cu/TEMPO mediator system that operates at 0.5 V lower electrode potential than the TEMPO-only mediated process. This difference, which arises from a different catalytic mechanism, rationalizes the broad functional group tolerance of Cu/TEMPO-based aerobic alcohol oxidation catalysts. Aminoxyl mediators address long-standing challenges in the Shono oxidation, an important method for alpha-C-H oxidation of tertiary amides and carbamates. Shono oxidations are initiated by a high-potential SET step that limits their utility. Aminoxylmediated Shono-type oxidations have been developed that operate at much lower potentials and tolerate diverse functional groups. Analogous reactivity underlies alpha-C-H cyanation of secondary cyclic amines, a new method that enables efficient diversification of piperidine-based pharmaceutical building blocks and preparation of non-natural amino acids. Electrochemical oxidations of benzylic C-H bonds are commonly initiated by SET to generate arene radical cations, but such methods are again plagued by large overpotentials. Mediated electrolysis methods that promote hydrogen-atom-transfer (HAT) from benzylic C-H bonds to Fe-oxo species and phthalimide N-oxyl (PINO) support C-H oxygenation, iodination, and oxidative-coupling reactions. A complementary method merges photochemistry with electrochemistry to achieve amidation of C(sp(3))-H bonds. This unique process operates at much lower overpotentials compatible with diverse functional groups. These results have broad implications for organic electrochemistry, highlighting the importance of overpotential considerations and the prospects for expanding synthetic utility by using mediators to bypass high-energy outer-sphere electron-transfer mechanisms. Principles demonstrated here for oxidation are equally relevant to electrochemical reductions.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3040-44-6 is helpful to your research. Computed Properties of C7H15NO.
