Well-Defined N-Heterocyclic Carbene-Palladium Complexes as Efficient Catalysts for Domino Sonogashira Coupling/Cyclization Reaction and C-H bond Arylation of Benzothiazole

Well-defined and air-stable PEPPSI (Pyridine Enhanced Precatalyst Preparation Stabilization and Initiation) themed palladium bis-N-heterocyclic carbene complexes have been developed for the domino Sonogashira coupling/cyclization reaction of 2-iodophenol with a variety of terminal alkynes and C-H bond arylation of benzothiazole with aryl iodides. The PEPPSI themed palladium complexes, 2a and 2b were synthesized in good yields from the reaction of corresponding imidazolium salts with PdCl2 and K2CO3 in pyridine. The new air-stable palladium-NHC complexes were characterized by NMR spectroscopy, X-ray crystallography, elemental analysis, and mass spectroscopy studies. The PEPPSI themed palladium(II) bis-N-heterocyclic carbene complexes 2a and 2b exhibited excellent catalytic activities for domino Sonogashira coupling/cyclization reaction of 2-iodophenol with terminal alkynes yielding benzofuran derivatives. In addition, the palladium complexes, 2a and 2b successfully catalyzed the direct C-H bond arylation of benzothiazole with aryl iodides as coupling partners in presence of CuI as co-catalyst.

Psoralen inhibits malignant proliferation and induces apoptosis through triggering endoplasmic reticulum stress in human SMMC7721 hepatoma cells

BackgroundPsoralen is a coumarin-like and coumarin-related benzofuran glycoside, which is a commonly used traditional Chinese medicine to treat patients with kidney and spleen-yang deficiency symptom. Psoralen has been reported to show estrogen-like activity, antioxidant activity, osteoblastic proliferation accelerating activity, antitumor effects and antibacterial activity. However, the antitumor mechanism of psoralen is not fully understood. This study aimed to investigate the therapeutic efficacy of psoralen in human hepatoma cell line SMMC7721 and the mechanism of antitumor effects.ResultsPsoralen inhibited proliferation of SMMC7721 in a dose- and time-dependent manner, and promoted apoptosis. Further, psoralen activated the ER stress signal pathway, including the expansion of endoplasmic reticulum, increasing the mRNA levels of GRP78, DDIT3, ATF4, XBP1, GADD34 and the protein levels of GDF15, GRP78, IRE1 alpha, XBP-1s in a time-dependent manner. Psoralen induces cell cycle arrest at G1 phase by enhancing CyclinD1 and reducing CyclinE1 expression. Moreover, TUDC couldn’t inhibit the psoralen-induced ER stress in SMMC7721 cells.ConclusionsPsoralen can inhibit the proliferation of SMMC7721 cells and induce ER stress response to induce cell apoptosis, suggesting that psoralen may represent a novel therapeutic option for the prevention and treatment hepatocellular carcinoma.

Bidirectional enantioselective synthesis of bis-benzofuran atropisomeric oligoarenes featuring two distal C-C stereogenic axes

We report the bidirectional enantioselective synthesis of bis-benzofuran atropisomeric oligoarenes featuring two distal C-C stereogenic axes obtained by a two-fold central-to-axial chirality conversion upon oxidative aromatization. The key enantioenriched centrally chiral bis-dihydrobenzofuran precursors were synthesized via a bidirectional diastereo- and enantio-selective organocatalyzed domino reaction between simple achiral and easily accessible dihydroxylated aromatics and chloronitroalkenes. Moreover, the stereodivergent nature of the methodology was established by synthesizing both diastereomers of a non-symmetrically functionalized bis-axially chiral oligoarene.

Ambrafuran (Ambrox(TM)) Synthesis from Natural Plant Product Precursors

Ambergris, an excretion product of sperm whales, has been a valued agent in the formulation of perfumes. The composition of ambergris consists of two major components: 40-46% cholestanol type steroids and approximately 25-45% of a triterpenoid known as ambrein. Ambergris undergoes oxidative decomposition in the environment to result in odorous compounds, such as ambraoxide, methylambraoxide, and ambracetal. Its oxidized form, ambrafuran (IUPAC name: 3a,6,6,9a-tetramethyl-2,4,5,5a,7,8,9,9b-octahydro-1H-benzo[e][1]benzofuran), is a terpene furan with a pleasant odor and unique olfactive and fixative properties. The current state of the fragrance industry uses ambrafuran materials entirely from synthetic or semisynthetic sources. However, natural compounds with the potential to be converted to ambergris-like odorants have been extracted from several different types of plants. Here we review plant terpenoids suitable as starting materials for the semisyntheses of ambrafuran or intermediates, such as ambradiol, that can be used in biocatalytic transformations to yield ambrafuran.

Synthesis and properties of novel 6,7-dihydrocyclopenta[5,6-b]benzofuran-based liquid crystal compounds

A novel liquid crystal core unit 6,7-dihydrocyclopenta[5,6-b]benzofuran was designed and three different kinds of liquid crystals2MUF, 2MP4, 2MYO2were synthesised through a facile route which employed palladium-catalysed cascade Sonogashira coupling/cyclisation as a key step. Initially, density function theory calculation illustrated that a compound based on this new unit possessed almost a linear structure. The mesophase and physical properties of these novel compounds were measured and the impacts of the newly designed core unit on these properties were investigated by comparing with two series of analogous materials which contained classical mesogenic cores 1,4-disubstituted benzene andtrans-cyclohexyl benzene, finding that the introduction of 6,7-dihydrocyclopenta[5,6-b]benzofuran into liquid crystals tended to promote the formation of nematic phase while increasing both the melting points and the clearing points of target molecules. Meanwhile, the newly synthesised liquid crystals presented higher birefringences when compared with their corresponding reference compounds, indicating that 6,7-dihydrocyclopenta[5,6-b]benzofuran can be a hopeful candidate for the construction of high birefringence liquid crystals.

Excited-state intramolecular proton transfer (ESIPT) emitters based on a 2-(2-hydroxybenzofuranyl)benzoxazole (HBBO) scaffold functionalised with oligo(ethylene glycol) (OEG) chains

This article describes the multi-step synthesis of 2-(2-hydroxybenzofuran)benzoxazole (HBBO) derivatives functionalised with one to three oligo(ethylene glycol) (OEG) chains with the goal to allow a good vectorization in aqueous media. Benzoxazole dyes are well-known organic fluorophores exhibiting excited-state intramolecular proton transfer (ESIPT) emission. The insertion of these highly hydrophilic OEG chains allows a good solubilization of these dyes in a wide range of solvents of different polarity including PBS buffer/DMSO (95/5) and water, for one of them. The photophysical properties of these ESIPT emitters in solution, and also in the solid-state, as doped as 1 wt% in poly(methylmethacrylate) (PMMA) or polystyrene (PS) films, are discussed. Specifically, the presence of an OEG chain at the 3-position of the benzofuran ring was found to sizeably enhance the fluorescence intensity of the ESIPT emission in the solution state.

Photovoltaic Performance of 4,8-Bis(2 ‘-ethylhexylthiophene)thieno[2,3-f]benzofuran-Based Dyes Fabricated with Different Donors in Dye-Sensitized Solar Cells

Thieno[2,3-f]benzofuran (BDF) has the advantages of a highly planarized structure, strong electron-donating ability, high hole mobility, good conjugation, and a wide spectral response range. In recent years, BDF has been widely used in organic solar cells, especially in bulk-heterojunction (BHJ) organic solar cells. In this work, a model molecule PSB-1 was synthesized based on this highly planar fragment and used as a photosensitizer in dye-sensitized solar cells (DSCs), then different aromatic amine donors such as triphenylamine (TPA), carbazole (CZ), and phenothiazine (PTZ) were introduced to the end of PSB-1, and a series of dyes PSB-2, PSB-3, and PSB-4 were designed and synthesized. After that, the relationship among the molecular structure, energy level, and photovoltaic performance of the benzo-[1,2-b:4,5-b’]dithiophene (BDT) dye was studied by theoretical calculations, photophysics, electrochemistry, and photovoltaic properties. The results show that the introduction of a strong donor can effectively improve the energy level, absorption spectrum, and photovoltaic performance of PSB-1. Through the preliminary test, we found that the energy conversion efficiency (photovoltaic conversion efficiency-PCE) of PSB-4 is up to 5.5%, which is nearly 90% higher than that of PSB-1 (PCE = 2.9%), while the introduction of a weak donor greatly weakens the effect, in which the PCE of PSB-3 is 3.5%, which is only 20% higher than that of the model molecule. By an analysis of the molecular frontier orbital distribution using theoretical calculations, we found that the electron cloud of the highest occupied orbital level (highest occupied molecular orbital-HOMO) of PSB-3 is mainly distributed on the BDF group so that the electron transfer of excited-state molecules mainly occurs from the BDF to the receptor (CA).

Electric Literature of 14400-67-0, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 14400-67-0 is helpful to your research.
