At the first time, we elaborated the method of synthesis of naphtho[1,2-b]benzofurans based on photoinduced reaction of acrylonitriles containing 2-arylbenzofuran fragment as part of 1,3,5-hexatriene system. The considered reaction proceeds via initial 6 pi-electrocyclization followed by [1,9]-H sigmatropic shift and final oxidative aromatization of central benzene ring. It was shown that 5,6-dihydronaphtho[1,2-b]benzofurans are key intermediates of studied process. The structures of obtained 5,6-dihydronaphtho[1,2- b]benzofuran and one of the target naphtho[1,2-b]benzofurans were confirmed by X-ray diffraction. (C) 2021 Elsevier Ltd. All rights reserved.

A synthesis of novel bis(sulfanediyl)bis(tetrahydropyrimido[4,5-b]quinoline-4,6-diones), linked to aryl, heteroaryl, and spirocyclic-oxindole moieties at position-5, as novel hybrid molecules was reported. 2,2′-(Butane-1,4-diylbis(sulfanediyl))bis(6-aminopyrimidin-4(1H)-one) was utilized as a precursor to our target compounds via a multicomponent reaction with two equivalents of both of the appropriate aldehyde and dimedone. The target compounds were alternatively obtained by bis-(alkylation) of the appropriate 5-aryl-2-thioxohexahydropyrimido[4,5-b]quinoline-4,6-dione with 1,4-dibromobutane in moderate basic medium.

As a promising biodegradable and biorenewable alternative to ubiquitous petrochemical plastics, poly(L-lactide) (PLLA) can be widely employed in biomedical and pharmaceutical fields. In this work, triblock copolymers, poly(L-lactide)-b-poly(2-methyl-1,3-propanediyl adipate)-b-poly(L-lactide) (PLLA-b-PMPA-b-PLLA)s, were synthesized by two-step polymerization from 2-methyl-1,3-propanediol (MP), adipic acid (AA) and L-lactide (LLA) as new biodegradable thermoplastic elastomers. The copolymers exhibited glass-transition temperature at below -40 degrees C and melting temperature at 140-160 degrees C. These copolymers showed much higher elongation at break and lower tensile modulus than those of PLLA. Enzymatic degradation tests of the obtained copolymers were performed using proteinase K and lipase PS as catalysts in hydrolysis reaction to demonstrate rapid degradation for these copolymers. Seawater biodegradability test was conducted for 28 days for each sample. The triblock copolymer and PMPA homopolymer were found to show about 50% biodegradation within 28 days representing very high biodegradable property in sea-water. (C) 2020 The Authors.

Liquid liquid equilibrium (LLE) data for ternary systems of methyl isopropyl ketone (MIPK) + 2,3-/3,4-/3,5-dimethylphenol + water was determined from 298.15 K to 338.15 K under 101.3 kPa in this work. Distribution coefficient and selectivity were calculated to investigate solvent extraction efficiency of dimethylphenol from water and their high values indicated that MIPK could extract dimethylphenols well. The NRTL and UNIQUAC models were applied to correlate experimental LLE data and related root-mean square deviations (RMSDs) were less than 0.5%. Additionally, the experimental data was predicted by COSMO-SAC model, and the corresponding RMSD values demonstrated that COSMO-SAC model can be applied as a predictive tool to calculate LLE data of the investigated ternary systems.

A highly efficient bifunctional catalyst of an s-triazine-based carbon-nitride-supported cobalt oxide is developed for the aerobic oxidation-Knoevenagel condensation tandem reaction of benzyl alcohol and malononitrile, whereby 96.4% benzyl alcohol conversion with nearly 100% selectivity towards benzylmalononitrile can be obtained in 6 h at 80 degrees C. The excellent catalytic performance derives from the high basicity of carbon nitride and strong redox ability of Co species induced by carbon nitride. The catalyst is also quite stable and can be reused without any regeneration treatment, whose product yield is only an 11.5% reduction after four runs.

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

A three-component cascade reaction for the synthesis of 1,3,4-selenadiazoles and their derivatives from arylaldehydes, hydrazine, and elemental selenium by using molecular iodine is reported. This strategy is operationally simple, well-suited to a wide range of functional groups, and provides the desired products in moderate to excellent yields. The proposed mechanism predicts that the reaction tolerated a radical process.

The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5.

The effect of introducing a lateral methyl substituent and the two different alkoxy terminal groups on the mesophase behavior of three-benzene-ring molecular core of azo-ester compounds bearing 2-methylbutoxy unit on the opposite terminal side (C1-C6) were explored. Their structures were confirmed by several spectroscopic techniques (Fourier transform infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance spectroscopy). The mesomorphic properties of these compounds were studied by differential scanning calorimetry, polarized optical microscopy, and small- and wide-angle X-ray scattering. Except for the un-substituted terminals (C1 and C4), all other derivatives are liquid crystalline, exhibiting enantiotropic nematic liquid crystal phase. The alteration of the alkoxy chain length from methoxy to butoxy at the phenyl ester terminal group (ring A) for each set of laterally-neat and laterally methyl-substituted mesogens decreases the nematic temperature range. A decrease in the mesophase temperature range is also observed when a lateral methyl substituent is incorporated into phenylazo ring of the mesogenic core (ring C). Optical study demonstrated that their absorption spectra are identical in shape due to the structural similarities of the mesogenic core. The corresponding fluorescence spectra exhibited blue-emission with the laterally methyl substituted compounds having a relatively higher fluorescence intensity compared to that of its laterally un-substituted analogues. Furthermore, the laterally methyl-substituted derivatives were subjected to the planar alignment and their dielectric and electro-optic properties were investigated. The nematic phase of the aligned samples shows antiferroelectric switching behavior with spontaneous polarization, P-s similar to 5 mu C/cm(2). (C) 2021 Elsevier B.V. All rights reserved.

A metal- and additive-free methodology for the highly selective, photocatalyzed C-H oxygenation of alkylarenes under air to the corresponding carbonyls is presented. The process is catalyzed by an imide-acridinium that forms an extremely strong photooxidant upon visible light irradiation, which is able to activate inert alkylarenes such as toluene. Hence, this is an easy to perform, sustainable and environmentally friendly oxidation that provides valuable carbonyls from abundant, readily available compounds.
