Tetraketones with their diversified biological potencies became a highly significant class of oxygen-containing organic compounds. These are prepared by applying a simple Knoevenagel-Michael cascade procedure with 1,3-dicarbonyl compound and aldehydes. In the due course of time, numerous methods for the synthesis of these compounds, have been developed which having their own advantages and disadvantages. So, the development of an efficient, simple, and ecologically benign method for their preparation in the presence of the novel catalytic agent is still in great demand. In the present report, direct crystals of 2,2 ‘-(arylmethylene)bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one) (a tetraketone) were obtained via a simple procedure using 2-aminopyrazine as a catalyst. The prepared compound shows significant antioxidant checked by different procedures like DPPH, ABTS, and TAC. [GRAPHICS] .

An efficient and green protocol for aerobic oxidation of benzylic alcohols in ethanol using Cu-I-Y zeolite catalysts assisted by TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidine-N-oxyl) as the radical co-catalyst in the presence of atmospheric air under mild conditions is reported. The Cu-I-Y zeolite prepared via ion exchange between CuCl and HY zeolite was fully characterized by a variety of spectroscopic techniques including XRD, XPS, SEM, EDX and HRTEM. The incorporation of Cu(i) into the 3D-framework of the zeolite rendered the catalyst with good durability. The results of repetitive runs revealed that in the first three runs, there was hardly a decline in activity and a more substantial decrease in yield was observed afterwards, while the selectivity remained almost unchanged. The loss in activity was attributed to both the formation of CuO and the bleaching of copper into the liquid phase during the catalysis, of which the formation of CuO was believed to be the major contributor since the bleaching loss for each run was negligible (<2%). In this catalytic system, except TEMPO, no other additives were needed, either a base or a ligand, which was essential in some reported catalytic systems for the oxidation of alcohols. The aerobic oxidation proceeded under mild conditions (60 degrees C, and 18 hours) to quantitatively and selectively convert a wide range of benzylic alcohols to corresponding aldehydes, which shows great potential in developing green and environmentally benign catalysts for aerobic oxidation of alcohols. The system demonstrated excellent tolerance against electron-withdrawing groups on the phenyl ring of the alcohols and showed sensitivity to steric hindrance of the substrates, which is due to the confinement of the pores of the zeolite in which the oxidation occurred. Based on the mechanism reported in the literature for homogenous oxidation, a mechanism was analogously proposed for the aerobic oxidation of benzylic alcohols catalysed by this Cu(i)-containing zeolite catalyst.

Here, we report the reaction between N-phenyl-o-phenylenediamine and pyrrole-2-carboxaldehyde to afford the N-phenyl-o-phenyl-enediiminopyrrole ligand {L-H2} in quantitative yield. A one-pot reaction between {L-H2} and diethylzinc (ZnEt2) in a 2:1 ratio afforded the homoleptic zinc metal complex [{L-H}(2)Zn] (1). The solid-state structures of ligand {L-H2} and zinc complex 1 were confirmed using X-ray crystallography. Further, complex 1 was used for chemoselective hydroboration of aldehydes and ketones in the presence of pinacolborane (HBpin) at ambient temperature to produce the corresponding boronate esters in high yield.

Herein, a dual nickel/ruthenium strategy is developed for photoinduced decarboxylative cross-coupling between alpha,beta-unsaturated carboxylic acids and cycloketone oxime esters. The reaction mechanism is distinct from previous photoinduced decarboxylation of alpha,beta-unsaturated carboxylic acids. This reaction might proceed through a nickelacyclopropane intermediate. The C(sp(2))-C(sp(3)) bond constructed by the aforementioned reaction provides an efficient approach to obtaining various cyanoalkyl alkenes, which are synthetically valuable organic skeletons in organic and medicinal chemistry, under mild reaction conditions. The protocol tolerates many critical functional groups and provides a route for the modification of complex organic molecules.

The paper reports the successful synthesis of microcapsules that incorporate thermally-reversible Diels-Alder or oxime-urethane bonds within the polymer of the microcapsule shell using an interfacial polymerisation technique. The mechanical strength of these microcapsules was found to be dependent on the structure of the thermally-reversible functionality, thus allowing for the design of strong microcapsules that demonstrated excellent stability in one-pot PU formulations. Release of the encapsulated isocyanate crosslinkers using a thermal stimulus demonstrated the potential of this technology for use in the controlled polymerisation of one-pot PU systems.

Self-sustained Ni-I/III cycles are established as a potentially general paradigm in photoredox Ni-catalyzed carbon-heteroatom cross-coupling reactions through a strategy that allows us to recapitulate photoredox-like reactivity in the absence of light across a wide range of substrates in the amination, etherification, and esterification of aryl bromides, the latter of which has remained, hitherto, elusive under thermal Ni catalysis. Moreover, the accessibility of esterification in the absence of light is especially notable because previous mechanistic studies on this transformation under photoredox conditions have unanimously invoked energy-transfer-mediated pathways.

Background: Glycogen synthase kinase-3 (GSK-3) is involved in the phosphorylation and inactivation of glycogen synthase. GSK-3 inhibitors have been associated with a variety of diseases, including Alzheimer’s disease (AD), diabetes type II, neurologic disorders, and cancer. The inhibition of GSK-3 beta isoforms is likely to represent an effective strategy against AD. Objective: The present work aimed to design and synthesize coumarin derivatives to explore their potential as GSK-3 beta kinase inhibitors. Methods: The through different synthetic methods were used to prepare coumarin derivatives. The GSK-3 beta activity was measured through the ADP-Glo (TM) Kinase Assay, which quantifies the kinase-dependent enzymatic production of ADP from ATP, using a coupled-luminescence-based reaction. A docking study was performed by using the crystallographic structure of the staurosporine/GSK-3 beta complex [Protein Data Bank (PDB) code: 1Q3D]. Results: The eleven coumarin derivatives were obtained and evaluated as potential GSK-3 beta inhibitors. Additionally, in silico studies were performed. The results revealed that the compounds 5c, 5d, and 6b inhibited GSK-3 beta enzymatic activity by 38.97-49.62% at 1 mM. The other coumarin derivatives were tested at 1 mM, 1 mu M, and 1 nM concentrations and were shown to be inhibitor candidates, with significant IC50 (1.224-6.875 mu M) values, except for compound 7c (IC50 – 10.809 mu M). Docking simulations showed polar interactions between compound 5b and Lys(85) and Ser(203), clarifying the mechanism of the most potent activity. Conclusion: The coumarin derivatives 3a and 5b, developed in this study, showed remarkable activity as GSK-3 beta inhibitors.

We report a pyridyl-phosphine ruthenium(II) catalyzed tandem alcohol amination/Pictet-Spengler reaction sequence to synthesize tetrahydro-beta-carbolines from an alcohol and tryptamine. Our conditions use a Lewis acid cocatalyst, In(OTf)(3), that is compatible with typically base catalyzed amination and an acid catalyzed Pictet-Spengler cyclization. This method proceeds well with benzylic alcohols, heterocyclic carbinols, and aliphatic alcohols. We also show how combining this reaction with a subsequent cycloamination enables a direct synthesis of tetracyclic alkaloids like harmicine.

The widespread presence of secondary amines in agrochemicals, pharmaceuticals, natural products, and small-molecule biological probes has inspired efforts to streamline the synthesis of molecules with this functional group. Herein, we report an operationally simple, mild protocol for the synthesis of secondary amines by three-component alkylation reactions of imines (generated in situ by condensation of benzaldehydes and anilines) with unactivated alkyl iodides catalyzed by inexpensive and readily available Mn-2(CO)(10). This protocol, which is compatible with a wide array of sensitive functional groups and does not require a large excess of the alkylating reagent, is a versatile, flexible tool for the synthesis of secondary amines.

Recommanded Product: 4′-Hydroxyacetophenone. I found the field of Chemistry very interesting.

A kinetic study on nucleophilic substitution reactions of 2,4-dinitrophenyl X-substituted-cinnamates (1a-1f) and Y-substituted-phenyl cinnamates (2a-2g) with a series of alicyclic secondary amines in MeCN at 25.0 +/- 0.1 degrees C is reported. The Bronsted-type plots for the reactions of 1a-1f are linear with beta(nuc) = 0.47 similar to 0.50, indicating that the bond formation between the amine nucleophile and the electrophilic center is advanced slightly in the transition state. The Bronsted-type plot for the reactions of 2a-2g with piperidine is also linear with beta(1g) = -0.66, which is a typical beta(1g) value for reactions reported previously to proceed through a concerted mechanism. Furthermore, the Hammett plot correlated with sigma-constants results in much better linearity than that correlated with sigma degrees constants, implying that expulsion of the leaving group is advanced in the rate-determining step (RDS). Thus, the reactions are concluded to proceed through a concerted mechanism. The Hammett plots for the reactions of 1a-1f consist of two intersecting straight lines, whereas the corresponding Yukawa-Tsuno plots exhibit excellent linear correlations with rho(X) = 0.62 similar to 0.71 and r = 0.65 similar to 0.68. Apparently, the nonlinear Hammett plots are not due to a change in the reaction mechanism (or the RDS) but are caused by stabilization of the substrate possessing an electron-donating group (EDG) in the cinnamoyl moiety through resonance interactions between the EDG and the C=O bond of the substrate. Medium effects on reactivity and reaction mechanism are also discussed.
