O-Quinone Methides via Oxone-Mediated Benzofuran Oxidative Dearomatization and Their Intramolecular Cycloaddition with Carbonyl Groups: An Expeditious Construction of the Central Tetracyclic Core of Integrastatins, Epicoccolide A, and Epicocconigrone A

The intramolecular cycloaddition of o-quinone methides (o-QMs) with a carbonyl group has been envisaged and executed successfully in the context of constructing the complex and rare [6,6,6,6]-tetracyclic core found in the integrastatins, epicoccolide A, and epicocconigrone A. These transient o-QMs were generated easily from the oxidative dearomatization of the corresponding C2-(aryl)benzofuran by employing Oxone in acetone-water at rt. The subsequent cycloaddition with the carbonyl (or conjugated olefin) present on the C2-aryl group was spontaneous.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 29040-52-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 29040-52-6, in my other articles.

Shape-stabilized composite phase change film with good reversible thermochromic properties fabricated: Via phase inversion-assisted impregnation

In this study, the regenerated porous cellulose film (LD) was properly prepared by dissolving cellulose in a LiCl/DMAc solvent though a simple phase inversion method. LD has a porous structure, good mechanical properties and great thermal stability. In order to form a shape-stabilized reversible thermochromic phase change film (DTLD), a reversible thermochromic compound (DTBC) was added into the LD by simple vacuum impregnation. The effect of the weight ratio of 1-dodecanol/tetradecanol complex solvent (3:7, 2:8, 1.5:8.5 and 1:9) on the phase change properties was investigated. DTLD (1.5:8.5) showed the highest latent heat storage of 174.00 J g-1 with the suitable phase change temperature at 37.5 C. The low thermal conductivity of DTLD (1.5:8.5) at 10 C (50 C) was 0.396 ¡À 0.004 W m-1 K-1 (0.408 ¡À 0.002 W m-1 K-1). The color of DTLD (1.5:8.5) can change reversibly between colorless and blue as temperature changes. Melting-cooling tests after 100 cycles indicated that DTLD (1.5:8.5) has a high latent heat storage capacity of 169.65 J g-1. A shape-stable reversible thermochromic phase change composite assembled from a regenerated porous cellulose membrane as a support matrix is expected to be applied to the field of thermal energy storage.

Enzymatic enantioselective decarboxylative protonation of heteroaryl malonates

The enzyme aryl/alkenyl malonate decarboxylase (AMDase) catalyses the enantioselective decarboxylative protonation (EDP) of a range of disubstituted malonic acids to give homochiral carboxylic acids that are valuable synthetic intermediates. AMDase exhibits a number of advantages over the non-enzymatic EDP methods developed to date including higher enantioselectivity and more environmentally benign reaction conditions. In this report, AMDase and engineered variants have been used to produce a range of enantioenriched heteroaromatic alpha-hydroxycarboxylic acids, including pharmaceutical precursors, from readily accessible alpha-hydroxymalonates. The enzymatic method described here represents an improvement upon existing synthetic chemistry methods that have been used to produce similar compounds. The relationship between the structural features of these new substrates and the kinetics associated with their enzymatic decarboxylation is explored, which offers further insight into the mechanism of AMDase. Versatile decarboxylase: Aryl malonate decarboxylase (AMDase) and engineered variants have been shown to catalyse the enatioselective decarboxylative protonation of a range of alpha-heteroaryl alpha-hydroxy malonates with excellent yields and enantioselectivity (see scheme).

Design and synthesis of 4-heteroaryl 1,2,3,4-tetrahydroisoquinolines as triple reuptake inhibitors

(Chemical Equation Presented) A series of 4-bicyclic heteroaryl 1,2,3,4-tetrahydroisoquinoline inhibitors of the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT) was discovered. The synthesis and structure-activity relationship (SAR) of these triple reuptake inhibitors (TRIs) will be discussed. Compound 10i (AMR-2), a very potent inhibitor of SERT, NET, and DAT, showed efficacy in the rat forced-swim and mouse tail suspension models with minimum e ffective doses of 0.3 and 1 mg/kg (po), respectively. At efficacious doses in these assays, 10i exhibited substantial occupancy levels at the three transporters in both rat and mouse brain. The study of the metabolism of 10i revealed the formation of a significant active metabolite, compound 13.

Oxidative Nanopatterning of Titanium Surface Influences mRNA and MicroRNA Expression in Human Alveolar Bone Osteoblastic Cells

Titanium implants have been extensively used in orthopedic and dental applications. It is well known that micro- and nanoscale surface features of biomaterials affect cellular events that control implant-host tissue interactions. To improve our understanding of how multiscale surface features affect cell behavior, we used microarrays to evaluate the transcriptional profile of osteoblastic cells from human alveolar bone cultured on engineered titanium surfaces, exhibiting the following topographies: nanotexture (N), nano+submicrotexture (NS), and rough microtexture (MR), obtained by modulating experimental parameters (temperature and solution composition) of a simple yet efficient chemical treatment with a H2SO4/H2O2 solution. Biochemical assays showed that cell culture proliferation augmented after 10 days, and cell viability increased gradually over 14 days. Among the treated surfaces, we observed an increase of alkaline phosphatase activity as a function of the surface texture, with higher activity shown by cells adhering onto nanotextured surfaces. Nevertheless, the rough microtexture group showed higher amounts of calcium than nanotextured group. Microarray data showed differential expression of 716 mRNAs and 32 microRNAs with functions associated with osteogenesis. Results suggest that oxidative nanopatterning of titanium surfaces induces changes in the metabolism of osteoblastic cells and contribute to the explanation of the mechanisms that control cell responses to micro- and nanoengineered surfaces.

Bio-based nickel alginate and copper alginate films with excellent flame retardancy: Preparation, flammability and thermal degradation behavior

A bio-based nickel alginate film and copper alginate film were prepared via a facile ion exchange and casting approach. Their flame retardancy, thermal degradation and pyrolysis behavior, and thermal degradation mechanism were investigated systematically by the limiting oxygen index (LOI), vertical burning (UL-94), microscale combustion calorimetry (MCC), thermogravimetric analysis (TGA), thermogravimetric analyzer coupled with Fourier transform infrared analysis (TG-FTIR) and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS). It was shown that the nickel alginate film had a much higher LOI value (50.0%) than those of the sodium alginate film (24.5%) and copper alginate film (23.0%). Moreover, the nickel alginate film passed the UL-94 V-0 rating, while the sodium alginate film and copper alginate film showed no classification. Importantly, the peak of heat release rate (PHRR) of the nickel alginate film in the MCC test was much lower than those of the copper alginate film and sodium alginate film. This indicated that the introduction of nickel ions decreased the release of combustible gases. TGA results showed that the addition of copper ions and nickel ions accelerated the thermal degradation of alginates and changed the thermal degradation mechanism of the alginates. TG-FTIR and Py-GC-MS results indicated that the pyrolysis of copper alginate and nickel alginate produced much less flammable products than that of sodium alginate in the whole thermal degradation process. Finally, a possible degradation mechanism for copper alginate and nickel alginate was proposed. The results of our study provide useful information for understanding the flame retardancy mechanism of alginate as well as for designing bio-based materials with excellent fire retardancy.
