An efficient synthesis of 1,3-dialkylidene-2,3-dihydro-1H-benzo[c]siloles, a new type of Si-bridged π-conjugated compounds, was developed from a simple substrate combination of dialkynylsilanes and arylboronic acids under Rh catalysis through the use of 1,4-Rh migration. The reaction pathway was probed by D-labeling experiments, and the use of o-tolylboronic acids gave 6-membered silacycles via 1,5-Rh migration.

Title compound I, labeled with ¹⁴C in the 2-position, was prepared in 30.7% yield by cyclocondensation of NH₂CH₂CH₂SH with ¹⁴C-labeled CH₂O in H₂O at pH = 8, followed by nitrosylation of the thiazolidine with NaNO₂ at pH = 4.5 adjusted with H₂SO₄. Adjustment of the pH in the latter step with HCl forms many disulfide byproducts.

Fronk, Stephanie L. published the artcileChiroptical Properties of a Benzotriazole-Thiophene Copolymer Bearing Chiral Ethylhexyl Side Chains, Synthetic Route of 21286-54-4, the publication is Macromolecules (Washington, DC, United States) (2016), 49(24), 9301-9308, database is CAplus.

Conjugated polymers containing alternating thiophene units and benzotriazole structural units bearing either chiral (S)-2-ethylhexyl (PBTz-Th*) or racemic 2-ethylhexyl side chains (PBTz-Th) were synthesized. Characterization by optical absorption spectroscopy of both PBTz-Th* and its racemic counterpart reveal aggregated chains, even at dilute concentrations in good solvents. The presence of a chiral substituent permits characterization via CD (CD) spectroscopy. CD spectra provide evidence of chiral aggregates of PBTz-Th* chains even at 0.01 mg/mL in dichlorobenzene. When PBTz-Th* solutions are diluted with PBTz-Th, the resulting CD spectrum suggests that PBTz-Th* chains are chiral in the aggregate. Chiral ordering is also found to translate from aggregates in solution to the solid state.

Yuan, Dan published the artcileThe enzyme-instructed assembly of the core of yeast prion Sup35 to form supramolecular hydrogels, Name: 2-Chlorotrityl chloride, the publication is Journal of Materials Chemistry B: Materials for Biology and Medicine (2016), 4(7), 1318-1323, database is CAplus and MEDLINE.

Based on the self-assembly capability of the core segment (GNNQQNY) of yeast prion Sup35, we design and synthesize a series of structurally related precursors for the enzymic formation of hydrogels. We found that, with the catalysis of alk. phosphatase, the precursor becomes a hydrogelator that self-assembles in water to form nanofibers with an average width less than ten nanometers. Interestingly, the introduction of an amyloid segment into a cytotoxic precursor (N’ffyp: D-1P) is able to abrogate the cytotoxicity of the precursor, making the resulting peptide cell compatible. This work contributes a new insight into the use of enzymes to form cell compatible hydrogels of peptide cross-β spine.

A visible-light photoinduced ring opening of N-alkyl-4-piperidinols under mild conditions was achieved. The reaction sequence involved a visible-light-induced charge-transfer complex, which promoted the S-Cl bond cleavage of sulfonyl chlorides.

Jonnalagadda, S. B. published the artcileKinetics and mechanism of the oxidation of methylene violet by bromate at acidic pH and the dual role of bromide ion, Application of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride, the publication is Journal of Physical Chemistry A (2009), 113(19), 5540-5549, database is CAplus and MEDLINE.

A phenazinium-type dye during oxidation by bromate ion under acidic conditions exhibited a complex nonlinear behavior. The intricate kinetics of reaction of 3-amino-7-(dimethylamino)-5-phenylphenazium chloride (MV⁺) with acidic bromate was investigated using the stopped flow technique. Under excess acid and bromate concentration conditions, MV⁺ exhibited a very slow reaction initially but a very rapid reaction after an induction time. The reaction had first-order dependence on both H⁺ and BrO₃^– ions. The overall stoichiometric reaction is 2MV⁺ + 2BrO₃^– + H2O → 2MP + 2HONEt₂ + N₂O + 2H⁺ + 2Br^–, where MP is dioxophenylphenazine. The active roles of various bromo and oxybromo species in the mechanism are discussed. The rapid kinetics of the direct reaction of bromine with MV⁺ is also reported. A 19-step mechanism, consistent with the exptl. data and validated by simulations using Simkine-2, is proposed.
