Pd-catalyzed C-H bond activation of Indoles for Suzuki reaction

We present a practical method for Suzuki coupling by which unprotected or N-protected indoles may be selectively arylated in the C2-position through direct C-H bond activation by electrophilic Pd(TFA)2 catalyst. The protocol is operationally simple as it is carried out in dioxane/water mixture, and air as the sole oxidant at room temperature. Various 2-arylated indoles were obtained in good yields. The protocol works for benzofuran, pyrrole and thiophene also. Graphic abstract Selective C-2 arylation of heterocycles using Pd(II) catalyst via C-H activation was performed under ambient condition. C3-C2 migration of organopalladium intermediate controls the reaction pathway.Computed Properties of C13H22N4O3S.

Biosynthesis of Stereoisomers of Dill Ether and Wine Lactone by Pleurotus sapidus

The white-rot fungus Pleurotus sapidus (PSA) biosynthesizes the bicyclic monoterpenoids 3,6-dimethyl-2,3,3a,4,5,7a-hexahydrobenzofuran (dill ether) (1) and 3,6-dimethy1-3a,4,5,7a-tetrahydro-1-benzofuran-2(3H)-one (wine lactone) (2). Submerged cultures grown in different media were analyzed by gas chromatography-mass spectrometry. The stereochemistry of the formed isomers was elucidated by comparing their retention indices to those of reference compounds by enantioselective multidimensional gas chromatography. The basidiomycete produced the rare (3R,3aR,7aS) and (3S,3aR,7aS) stereoisomers of dill ether and wine lactone. Kinetic analyses of the volatilome and bioprocess parameters revealed that the biosynthesis of the bicyclic monoterpenoids correlated with the availability of the primary carbon source glucose. Spiking the media with C-13 -labeled glucose demonstrated that the compounds were produced de novo. Supplementation studies i.a. with isotopically labeled substrates further identified limonene and p-menth-1-en-9-ol as intermediate compounds in the fungal pathways. PSA was able to biotransform all enantiomeric forms of the latter compounds to the respective isomers of dill ether and wine lactone.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 174775-48-5 help many people in the next few years. COA of Formula: C11H11NO3.

A phenyliodine(III) diacetate (PIDA)/CuBr-mediated construction of the novel 3H,3’H-spiro[benzofuran-2,2′-benzo[b]thiophene]-3,3′-dione skeleton was realized from the reaction of (Z)-3-hydroxy-1-(2-hydroxyphenyl)-3-(2-halogenphenyl)prop-2-en-1-ones with potassium ethylxanthate in the presence of 1,10-phen. The reaction sequence was postulated to encompass a PIDA-mediated oxidative C-O bond formation followed by a CuBr-mediated spirocyclization step.

Fusing acridine and benzofuran/benzothiophene as a novel hybrid donor for high-performance and low efficiency roll-off TADF OLEDs

Two novel acridine-benzofuran/benzothiophene hybrid donors of 34BxAc (x = F, 34BFAc: 13,13-dimethyl-8,13-dihydrobenzofuro[3,2-a]acridine; x = T, 34BTAc: 13,13-dimethyl-8,13-dihydrobenzo[4,5]thieno[3,2-a]acridine) were developed as aromatic fused donors by combining dimethyl acridine (Ac) with benzofuran and benzothiophene, respectively. As a comparison, the hybrid donors of 12BxAc (x = F, 12BFAc: 5,5-dimethyl-5,13-dihydrobenzofuro[3,2-c]acridine; x = T, 12BTAc: 5,5-dimethyl-5,13-dihydrobenzofuro[3,2-c]acridine) were also prepared. By attaching the TPPM (2,4,6-triphenylpyrimidine) acceptor to these fused hybrid donors (12BFAc, 12BTAc, 34BFAc and 34BTAc), 12BxAc-PM (12FAc-PM and 12BTAc-PM) and 34BxAc-PM (34BFAc-PM and 34BTAc-PM) were further designed and synthesized. It was revealed that 34BxAc-PM was better than 12BxAc-PM at shrinking the singlet-triplet energy gap and decay lifetime, and increasing the photoluminescence quantum yield. The sky-blue thermally activated delayed fluorescent organic light-emitting diodes (OLEDs) with 12BFAc-PM as a dopant just showed a maximum external quantum efficiency (EQE) of 12.9% and a CIEx,y of (0.16, 0.29). The 12BTAc-PM-based device achieved a maximum EQE of 25.6%, however, the efficiency roll-off was relatively serious. In contrast, high-performance and low efficiency roll-off OLEDs can be developed using 34BxAc-PM. For instance, the 34BFAc-PM-based device realized a maximum EQE of 27.7%, and still a high EQE of 24.6% at 1000 cd m(-2) and 19.6 cd m(-2) at 5000 cd m(-2), respectively, indicative of the superiorities of the novel donors (34BFAc and 34BTAc).

Tuning the organic persistent room-temperature phosphorescence through aggregated states

Persistent (long-lived) room-temperature phosphorescence (pRTP) materials from a single molecule with different polymorphs are rarely reported and need to be further investigated. In the current work, we have designed and synthesized an asymmetric molecule composed of carbazole and benzofuran based D-A-D ‘ pRTP materials, i.e., (4-(9H-carbazol-9-yl)phenyl)(dibenzo[b,d]furan-2-yl)methanone (DBF-BZ-Cz). The compound DBF-BZ-Cz exhibits different polymorphs with various pRTP properties, including a difference in their phosphorescence color and lifetimes. The tuning of long-lived phosphorescence of a simple compound through controlling the aggregated state is shown for the first time. The color of its pRTP changed from light-yellow to orange, while its pRTP lifetime shifted from 0.76 to 0.32 s. Furthermore, it is noted that a clear negative correlation between the fractional free volume (FFV) in the crystals and the pRTP lifetime can be drawn out for the ketone derivatives. The current work demonstrates that the pRTP properties can be tuned in one single compound via controlling the aggregated states, which provides a new strategy for the investigation and application of organic long-lived phosphorescence.

Synthesis and biological evaluation of 3-functionalized 2-phenyl- and 2-alkylbenzo[b]furans as antiproliferative agents against human melanoma cell line

The key function of microtubules and mitotic spindle in cell division make them attractive targets in anticancer therapy. In the present study, functionalized in 3 position 2-phenyl- and 2-alkylbenzo[b]furans were synthesized and evaluated as antitumor agents. Among the synthesized derivatives 13a, 13b and 14 exhibited the most potent antiproliferative activity against human melanoma A375 cell line with IC50 values of 2.85 mu M, 0.86 mu M, 0.09 mu M, respectively. The most promising compound defined was 14 with three methoxy groups in the 3-aroyl substituent and 7-methoxy group in 2-phenylbenzo[b]furan skeleton. Tubulin polymerization assay, confocal microscopy imaging and flow cytometry analysis revealed that 2-phenyl-3-aroylbenzo[b]furans (13a, 13b and 14) inhibited tubulin polymerization leading to disruption of mitotic spindle formation, cell cycle arrest in G2/M phase and apoptosis.

Discovery of novel benzofuran-based compounds with neuroprotective and immunomodulatory properties for Alzheimer’s disease treatment

To address the multifactorial nature of Alzheimer’s Disease (AD), a multi-target-directed ligand approach was herein developed. As a follow-up of our previous studies, a small library of newly designed 2-arylbenzofuran derivatives was evaluated towards cholinesterases and cannabinoid receptors. The two most promising compounds, 8 and 10, were then assessed for their neuroprotective activity and for their ability to modulate the microglial phenotype. Compound 8 emerged as able to fight AD from several directions: it restored the cholinergic system by inhibiting butyrylcholinesterase, showed neuroprotective activity against A beta(1-42) oligomers, was a potent and selective CB2 ligand and had immunomodulatory effects, switching microglia from the pro-inflammatory M1 to the neuroprotective M2 phenotype. Derivative 10 was a potent CB2 inverse agonist with promising immunomodulatory properties and could be considered as a tool for investigating the role of CB2 receptors and for developing potential immunomodulating drugs addressing the endocannabinoid system.
