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.

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 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.

Transition metal-catalyzed skeletal rearrangement reactions have rapid advances in organic community. Their development benefits synthetic methodologies by providing versatile and flexible approaches toward special molecular scaffolds with high selectivity. Herein, a gold-catalyzed skeletal rearrangement of alkenes with alkynyl bromides is reported, enabling direct and regioselective generation of more than 50 examples of skeletally diverse tricyclic heterocycles, namely, syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines, with generally good yields. This protocol could tolerate terminal unactivated and internal activated alkenes under air conditions, which is hitherto unreported in gold catalysis and scarcely realized by other metal-catalyzed reactions, thus opening avenues for the regioselective assembly of heterocyclic systems with high efficiency. Aside from examining the scope of this skeletal rearrangement, mechanistic investigations to explain the regioselectivity of forming syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines were conducted by systematic theoretical calculations.

The use of the N-phosphinoamidinato NHC-diborene catalyst 2 for hydroboration is described. The N-phosphinoamidine tBu(2)PN(H)C(Ph)=N(2,6-iPr(2)C(6)H(3)) was reacted with nBuLi in Et2O to afford the lithium derivative, which was then treated with B2Br4(SMe2)(2) in toluene to form the N-phosphinoamidinate-bridged diborane 1. It was reacted with the N-heterocyclic carbene IMe (:C{N(CH3)C(CH3)}(2)) and excess potassium graphite at room temperature in toluene to give the N-phosphinoamidinato NHC-diborene compound 2. It can stoichiometrically activate ammonia-borane and carbon dioxide. It also showed catalytic capability. A 2 mol % portion of 2 catalyzed the hydroboration of carbon dioxide (CO2) with pinacolborane (HBpin) in deuterated benzene (C6D6) at 110 degrees C (conversion >99%), which afforded the methoxyborane [pinBOMe] (yield 97.8%, TOF 33.3 h(-1)) and the bis(boryl) oxide [(pinB)(2)O]. In addition, 5 mol % of 2 catalyzed the N-formylation of secondary and primary amines by carbon dioxide and pinacolborane to yield the N-formamides (average yield 91.6%, TOF 25.9 h(-1)). Moreover, 2 showed chemoselectivity toward catalytic hydroboration of carbonyl compounds. In mechanistic studies, the B=B double bond in compound 2 activated the substrates, the intermediates of which then underwent hydroboration with pinacolborane to yield the products and regenerate catalyst 2.

Many shreds of evidence have recently correlated A2B receptor antagonism with anticancer activity. Hence, the search for an efficient A2B antagonist may help in the development of a new chemotherapeutic agent. In this article, 23 new derivatives of [1,2,4]triazolo[4,3-a]quinoxaline were designed and synthesized and its structures were confirmed by different spectral data and elemental analyses. The results of cytotoxic evaluation of these compounds showed six promising active derivatives with IC(50)values ranging from 1.9 to 6.4 mu M on MDA-MB 231 cell line. Additionally, molecular docking for all synthesized compounds was performed to predict their binding affinity toward the homology model of A2B receptor as a proposed mode of their cytotoxic activity. Results of molecular docking were strongly correlated with those of the cytotoxic study. Finally, structure activity relationship analyses of the new compounds were explored. [GRAPHICS] .

The complex pathogenesis of Alzheimer’s disease (AD) has become a major obstacle in its therapy. One hopeful approach is to develop multifuntional ligands. Here, a total of 23 compounds based on nobiletin structure were designed and synthesized. The neuroprotective activities were evaluated for their antioxidant, anti-inflammatory and anti-A beta(42) (Amyloid beta-protein 42) neurotoxicity properties by MTT assays. The results demonstrated compound A12 was the most promising derivative against inflammatory (14.6 +/- 0.6 %) and cell damages induced by hydrogen peroxide (47.2 +/- 1.1 %), oxygen glucose deprivation (36.2 +/- 1.1 %) and A beta(42) (40.7 +/- 2.1 %). Molecular docking study revealed A12 formed a greater area of interactions with A beta(42) to prevent it from acquiring a beta sheet conformation for aggregation. Structure-activity relationships revealed the introduction of hydroxyl on ring B and aurone skeleton with a five-membered ring C could be benefit to increase their neuroprotective activities. In summary, A12 might represent a promising multifunctional neuroprotective agent against AD.

Owing to hindered diffusions, the application of porous catalytic materials has been limited to relatively simple organic transformations with small substrates. Herein we report a dimensional reduction strategy to construct a two-dimensional metal-organic framework (MOF), Zr6OTf-BTB, with 96% accessible Lewis acidic sites as probed by the bulky Lewis base pivalonitrile. With nearly free substrate accessibility, Zr6OTf-BTB outperformed two three-dimensional MOF counterparts of similar Lewis acidity (Zr6OTf-BPDC and Zr6OTf-BTC) in catalyzing sterically hindered multicomponent reactions (MCRs) for the construction of tetrahydroquinoline and aziridine carboxylate derivatives with high turnover numbers (TONs). Zr6OTf-BTB was also superior to the homogeneous benchmark Sc(OTf)(3) with nearly 14 times higher TON and 9 times longer catalyst lifetime. Furthermore, the topology-activity relationships in these Zr-based Lewis acidic MOFs were rationalized by comparing their Lewis acidity, numbers of Lewis acidic sites, and sterically accessible Lewis acidic sites. Zr6OTf-BTB was successfully used to construct several bioactive molecules via MCRs with excellent efficiency. This dimensional reduction strategy should allow the development of other MOF catalysts for synthetically useful and complicated organic transformations.
