The paper reports the successful synthesis of microcapsules that incorporate thermally-reversible Diels-Alder or oxime-urethane bonds within the polymer of the microcapsule shell using an interfacial polymerisation technique. The mechanical strength of these microcapsules was found to be dependent on the structure of the thermally-reversible functionality, thus allowing for the design of strong microcapsules that demonstrated excellent stability in one-pot PU formulations. Release of the encapsulated isocyanate crosslinkers using a thermal stimulus demonstrated the potential of this technology for use in the controlled polymerisation of one-pot PU systems.

Self-sustained Ni-I/III cycles are established as a potentially general paradigm in photoredox Ni-catalyzed carbon-heteroatom cross-coupling reactions through a strategy that allows us to recapitulate photoredox-like reactivity in the absence of light across a wide range of substrates in the amination, etherification, and esterification of aryl bromides, the latter of which has remained, hitherto, elusive under thermal Ni catalysis. Moreover, the accessibility of esterification in the absence of light is especially notable because previous mechanistic studies on this transformation under photoredox conditions have unanimously invoked energy-transfer-mediated pathways.

A kinetic study on nucleophilic substitution reactions of 2,4-dinitrophenyl X-substituted-cinnamates (1a-1f) and Y-substituted-phenyl cinnamates (2a-2g) with a series of alicyclic secondary amines in MeCN at 25.0 +/- 0.1 degrees C is reported. The Bronsted-type plots for the reactions of 1a-1f are linear with beta(nuc) = 0.47 similar to 0.50, indicating that the bond formation between the amine nucleophile and the electrophilic center is advanced slightly in the transition state. The Bronsted-type plot for the reactions of 2a-2g with piperidine is also linear with beta(1g) = -0.66, which is a typical beta(1g) value for reactions reported previously to proceed through a concerted mechanism. Furthermore, the Hammett plot correlated with sigma-constants results in much better linearity than that correlated with sigma degrees constants, implying that expulsion of the leaving group is advanced in the rate-determining step (RDS). Thus, the reactions are concluded to proceed through a concerted mechanism. The Hammett plots for the reactions of 1a-1f consist of two intersecting straight lines, whereas the corresponding Yukawa-Tsuno plots exhibit excellent linear correlations with rho(X) = 0.62 similar to 0.71 and r = 0.65 similar to 0.68. Apparently, the nonlinear Hammett plots are not due to a change in the reaction mechanism (or the RDS) but are caused by stabilization of the substrate possessing an electron-donating group (EDG) in the cinnamoyl moiety through resonance interactions between the EDG and the C=O bond of the substrate. Medium effects on reactivity and reaction mechanism are also discussed.

Precise freeform microchannels within an aqueous environment have several biomedical applications but remain a challenge to fabricate. Carbohydrate glass materials have shown potential for three-dimensionally (3D) printing precise, microscale structures and are suitable as a sacrificial material to reconstruct complex channel architectures, but due to the rapid dissolution kinetics in hydrogels and the aqueous environment, protective coatings are required. Here, conformal coatings were applied to carbohydrate structures via surface-initiated photo-polymerization (SIP) by incorporating a photoinitiator (PI) into freeform 3D printed isomalt structures using a custom 3D printer. Structures were then immersed into a photocurable prepolymer bath and exposed to light for reaction initiation. To achieve uniform distribution of photoinitiator molecules in 3D printed constructs, miscibility between commercial photoinitiators and isomalt was modeled using the group contribution method. A dye-based, type-two photoinitiator, Eosin Y disodium salt (EY), was selected for its miscibility with isomalt and stability under high temperature. A previously described Eosin Y (EY)/triethanolamine (TEA) radical polymerization system was used to polymerize poly(ethylene glycol) diacrylate (PEGDA). Attenuated total reflectance-Fourier transform infrared (ATR-FTIR), surface morphology, and swelling ratio characterizations via SIP were performed. Coatings around freeform structures and solid surfaces were presented to demonstrate the capability of coating complex architectures. This coating method should facilitate the application of 3D sacrificial molding in a variety of hydrogels toward building biomimetic vascular constructs.

Chlorine is the 20th most abundant element on the earth compared to bromine, iodine, and fluorine, a sulfonimide reagent, N-chloro-N-(phenylsulfonyl)benzenesulfonamide (NCBSI) was identified as a mild and selective oxidant. Without activation, the reagent was proved to oxidize primary and secondary alcohols as well as their symmetrical and mixed ethers to corresponding aldehydes and ketones. With recoverable PS-TEMPO catalyst, selective oxidation over chlorination of primary and secondary alcohols and their ethers with electron-donating substituents was achieved. The reagent precursor of NCBSI was recovered quantitatively and can be reused for synthesizing NCBSI. (C) 2021 Elsevier Ltd. All rights reserved.

The phytochemical studies on the aerial parts of Digitalis davisiana Heywood led to the isolation of three undescribed phenylethanoid glycosides named as digidavisoside A (5), digidavisoside B (7), and davisoside (8), along with 9 known compounds, ferruginoside B (1), isolugrandoside (2), lugrandoside (3), maxoside (4), 3 ””-O-methylmaxoside (6), trans-lamiuside E (9), digiciliside B (10), p-hydroxyacetophenone (11), and chrysoeriol (12). For the first time compound 11 was reported for Digitalis genus. The chemotaxonomical significance of these compounds in Plantaginaceae family was evaluated and 3′-O-glucosyl substituted phenylethanoid glycosides 4-8 and 10 were found to be chemotaxonomically important for the family. Cytotoxic activity of the aqueous fraction of the methanolic extract was also tested against HEp-2 (human larynx epidermoid carcinoma) and HepG2 (human hepatocellular carcinoma) cancer cell lines. The aqueous fraction showed stronger cytotoxicity on HEp-2 cells than on HepG2. Therefore, the cytotoxic activity of 1-4, 6, 7 and 9 were tested against HEp-2 and L929 (mouse fibroblast cell) cell lines. Other isolated compounds could not be tested due to their insufficient amount. The results were evaluated in the point of structure-activity relationships. IC50 values against HEp-2 cells were established in a range of 71.9-220 mu M. Maxoside (4), isolugrandoside (2) and lugrandoside (3) showed higher cytotoxicity against HEp.2 cell line than other isolated compounds.

Here, we have demonstrated visible light-emitting diode light-driven selective and efficient aerobic oxidation of primary/secondary alcohols to aldehydes/ketones and oxidative azo-coupling of anilines using biomass rice husk-derived chemically activated carbon sheet-supported copper-iron bimetallic hybrid nanomaterials (CuxFe1-x@ RCAC) under oxidant and additive-free conditions. The catalytic activity of the CuxFe1-x@RCAC materials has been investigated for the oxidation of alcohols and anilines, and Cu0.9Fe0.1@RCAC was established as the best catalyst. Moreover, a tandem one-pot protocol has been developed for the sequential oxidation of alcohols followed by condensation to functionalized imidazole and imine derivatives in high isolated yields. The hybrid materials were highly robust and stable under the reaction conditions and were recovered simply by filtration and recycled up to 12th run without considerable loss in catalytic activity.

A nickel-catalyzed reductive coupling of aryl triflates with thiocarbonates is reported here. Both electron-rich and -deficient aryl C(sp(2))-O electrophiles as well as a class of O-tBu S-alkyl thiocarbonates are compatible with the optimized reaction conditions, as evidenced by 49 examples. The reaction also proceeds with good chemoselective cleavage of the C-O bond with regard to thioesters. This work broadens the scope of nickel-catalyzed reductive cross-electrophile coupling reactions.

Indole chalcones were designed and synthesized as a promising set of compounds against H(37)Rv strain of Mycobacterium tuberculosis. Within this library of compounds, (E)-1-(furan-3-yl)-3-(1H-indol-3-yl)prop-2-en-1-one (18), (E)-3-(1H-indol-3-yl)-1-(thiophen-2-yl)prop-2-en-1-one (20) and (E)-2-((1H-indol-2-yl)methylene)cyclopentan-1-one (24) displayed high anti-tubercular activity at 50 mu g/ml with MIC values of 210, 197 and 236 mu M respectively. The in-silico studies revealed that compound 18 exhibit binding modes similar to FAS-II inhibitors like INH or Thiolactomycin against KasA protein. Cytotoxicity assay results suggest that the compounds 18, 20 and 24 are non-cytotoxic to human megakaryocytes and murine B cells. (C) 2020 Elsevier Masson SAS. All rights reserved.
