TL;DR: In this article, a mechanism was proposed for the selective oxidative cyclization of 3-carboxyprqpyl radicals to γ-butyrolactone when using the Na2S2O8-CuSO4 oxidation system.
Abstract: A mechanism was proposed for the selective oxidative cyclization of 3-carboxyprqpyl radicals to γ-butyrolactone when using the Na2S2O8-CuSO4 oxidation system. In this mechanism the Cu(III) ions take part in the reaction.

TL;DR: In this article, the relative content of an individual chloroalkanonitrile in the mixture of isomers increased depending on the extent of removal of the radical center from the CN group in the intermediate cyanoalkyl radicals, reaching a maximum on substitution at the (ω-1)-th carbon atom.
Abstract: 1 Oxidative chlorination of alkanonitriles CH3(CH2)nCN (n=2–6) with sodium persulfate in the presence of an equimolar quantity of copper chloride in water and in hydrochloric acid occurred at each carbon atom of the alkyl chain with the exception of theα position 2 On reaction in water the relative content of an individual chloroalkanonitrile in the mixture of isomers increased depending on the extent of removal of the radical center from the CN group in the intermediate cyanoalkyl radicals, reaching a maximum on substitution at the (ω-1)-th carbon atom 3 On reaction in hydrochloric acid 5-chloroalkanonitriles were formed predominantly which indicated the intramolecular participation of the cyano group in the generation of the intermediate 4-cyanoalkyl radicals

TL;DR: In this paper, the Hoffmann type rearrangement in a Na2S2O8-NaCl-NaOH system was used to convert the alkanoic acid amides into amines containing one carbon atom less than the initial amides.
Abstract: 1. Unsubstituted alkanoic acid amides R(CH2)4CONH2 (R=H or alkyl) convert in Na2S2O8-CuCl2 and Na2S2O8-NaCl oxidation systems via intermediate amidyl radicals R(CH2)4C(O)NH intoγ- and δ-lactones with a considerable predominance ofγ-lactones. 2. Monoalkyl amides of alkanoic acids are lactonized to an inappreciable extent by the action of the S2O82−-Cl− system; N,N-diethyl valeramide undergoes oxidative dealkylation into N-alkyl valeramide. 3. As the result of an oxidative, Hoffmann type rearrangement in a Na2S2O8-NaCl-NaOH system, unsubstituted alkanoic acid amides convert into amines containing one carbon atom less than the initial amides.

TL;DR: In this paper, a method of treating a HCV infection in a subject comprises administering to the subject a therapeutically effective amount of a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof.
Abstract: A compound is represented by Structural Formula (I), or a pharmaceutically acceptable salt thereof, wherein the variables of Structural Formula (I) are as described in the specification and the claims. A pharmaceutical composition comprises a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier of excipient. A method of treating a HCV infection in a subject comprises administering to the subject a therapeutically effective amount of a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof. A method of inhibiting or reducing the activity of HCV polymerase in a subject or in a biological in vitro sample comprises administering to the subject or to the sample a therapeutically effective amount of a compound represented by Structural Formula (I) or a pharmaceutically acceptable salt thereof.

TL;DR: In this paper, Fang et al. made thermodynamic measurements for the binary mixture of water + γ-valerolactone (GVL) and for pure GVL to facilitate the development of the technology of lignin removal from lignocellulosic biomass.
Abstract: Thermodynamic measurements were made for the binary mixture of water + γ-valerolactone (GVL) and for pure GVL to facilitate the development of the technology of lignin removal from lignocellulosic biomass (Fang, W.; Sixta, H. Advanced Biorefinery based on the Fractionation of Biomass in γ - Valerolactone and Water. ChemSusChem 2015, 8, 73−76). The density and vapor pressure of pure GVL as a function of temperature were measured and correlated for a wide range of the temperatures and pressures. Isothermal vapor–liquid equilibrium (VLE) data of the binary mixture of water + GVL were measured at 350.2 K with a static total pressure apparatus. Absence of an azeotrope was confirmed by circulation still measurements with diluted GVL solutions. Excess molar enthalpy (hE) of the mixture for the whole range of mole fractions including infinite dilution was measured using a SETARAM C80 calorimeter equipped with a flow mixing cell at 322.6 and 303.2 K. The VLE and hE data were used for the optimization of UNIQUAC an...
