In this work, 3-(2-bromoacetyl)-2H-chromen-2-ones prepared from 3-acetyl coumarins with tetrabutylammonium tribromide on bromination were used as the raw material. An efficient approach toward the synthesis of 4-(coumarin-3-yl)-2-arylaminothiazoles was carried out by the reaction of the starting compounds with certain Ph thioureas in presence of PEG-400 under ultrasound irradiation at a frequency of 40 kHz in 20âˆ?0 min, with a yield of 81.6%âˆ?3.0%. The structures of target compounds were confirmed by IR, ¹HNMR, ¹³CNMR, MS and elemental anal. Preliminary bioassay results showed that some of them have certain antibacterial activities against Staphylococcus aureus, Bacillus subtilis and Escherichia coli. This method is operationally simple and environmentally benign and the solvent could be reused for several times.

Lai, J. S. published the artcilePreparation of sulfur ylide complexes of platinum by phase transfer catalysis, Application of trimethyloxosulphonium chloride, the publication is Journal of Organometallic Chemistry (1990), 393(3), 431-40, database is CAplus.

Various sulfur ylide complexes of Pt were prepared by the phase transfer catalysis (PTC). Thus, reaction of Pt(PR₃)₂Cl₂ (R = Me, Ph) in CH₂Cl₂ with [S(O)(CH₃)₃]I under PTC/OH^– conditions give complexes {Pt(PR₃)₂[(CH₂)₂S(O)(CH₃)]}I, which contain a bidentate double sulfur ylide. With Pt(dppe)Cl₂ [dppe = Ph₂P(CH₂)₂PPh₂] as starting material, a similar product was obtained. But when Pt(dppm)Cl₂ [dppm = Ph₂PCH₂PPh₂] was treated with [S(O)(CH₃)₃]Cl under PTC/OH^– conditions, an unexpected product {Pt(PPh₂CH₃)(PPh₂OH)[(CH₂)₂S(O)(CH₃)]}Cl was obtained. This compound contains a bidentate double sulfur ylide and two unsym. phosphines resulting from the base hydrolysis of dppm. Compound {Pt(PPh₃)₂[(CH₂)₂S(O)(CH₃)]}I, was subjected to an x-ray diffraction study.

Chen, Cheng published the artcileDiscovery of cytochrome bc₁ complex inhibitors inspired by the natural product karrikinolide, Safety of 2-Chloro-4-methylphenylboronic acid, the publication is RSC Advances (2016), 6(100), 97580-97586, database is CAplus.

The cytochrome bc₁ complex (cyt bc₁ or complex III) is a promising target of numerous antibiotics and fungicides. With an aim to indentify new lead structures for the bc₁ complex, a series of novel inhibitors were discovered from the natural product karrikinolide for the first time. Extensive screening results suggested variable inhibitory activities of these compounds against succinate-cytochrome reductase [SCR, a mixture of respiratory complex II (SQR) and complex III (the bc₁ complex)], implying the essential role of a 4-substituted Ph group for the high potency. Exceptionally, compound 12g showed excellent inhibition potency having an IC₅₀ value in the sub-micromolar range, demonstrating its higher potency than the com. control amisulbrom by over two orders of magnitude. Further experiments inferred that these newly prepared compounds mainly target the bc₁ complex. Seemingly, this work has presented a new lead scaffold for further development of bc₁ complex inhibitors.

Jiang, Lianzhong published the artcileA photochromic dye doped polymeric Mach-Zehnder interferometer for UV light detection, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2019), 7(21), 6257-6265, database is CAplus.

Owing to the compact size, immunity to electromagnetic interference, high sensitivity and real-time monitoring, optical waveguide sensors based on a refractive index change have become an emerging approach for smart sensing in the internet-of-things system. For this purpose, the synergetic efforts in material engineering (sensing materials) and optical engineering (waveguide design and fabrication) are both indispensable. Here we report a Mach-Zehnder interferometer (MZI) waveguide with photochromic dye-doped polymer sensing films for UV light detection. Firstly, UV light induced photochromism of a synthesized dye DAECHO in solution and in the solid state is investigated to understand the relationship between their structure and optical properties, especially the photochromism-induced refractive index change for waveguide sensors. Then the MZI structure is designed and simulated to optimize the performance of refractive index sensing. Following the standard microfabrication process of double photolithog.-development, the device is fabricated with a DAECHO doped polymer as a sensing cladding material for UV light detection. The evanescent sensing of MZI is performed to detect weak UV light from 10 μW cm^-2 to 100 μW cm^-2 at 365 nm. Our demonstration of MZI for UV light detection indicates the potential of portable and highly sensitive UV light waveguide sensors for real-life applications.
