In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Identification and Biological Evaluation of a Series of 1H-Benzo[de]isoquinoline-1,3(2H)-diones as Hepatitis C Virus NS5B Polymerase Inhibitors, published in 2009-08-27, which mentions a compound: 3685-23-2, Name is cis-4-Aminocyclohexane carboxylic acid, Molecular C7H13NO2, Formula: C7H13NO2.

The hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase (RdRp) plays a central role in virus replication. NS5B has no functional equivalent in mammalian cells and, as a consequence, is an attractive target for inhibition. Herein, we present 1H-benzo[de]isoquinoline-1,3(2H)-diones as a new series of selective inhibitors of HCV NS5B polymerase. The HTS hit 1 shows submicromolar potency in two different HCV replicons (1b and 2b) and displays no activity on other polymerases (HIV-RT, Polio-pol, GBV-b-pol). These inhibitors act during the pre-elongation phase by binding to NS5B non-nucleoside binding site Thumb Site II as demonstrated by crystal structure of compound 1 with the ΔC55-1b and ΔC21-2b enzymes and by mutagenesis studies. SAR in this new series reveals inhibitors, such as 20, with low micromolar activity in the HCV replicon and with good activity/toxicity window in cells.

The electron transfer to peresters was studied by electrochem. means in N,N-dimethylformamide. The reduction was carried out by three independent methods: (i) heterogeneously, by using glassy carbon electrodes, (ii) homogeneously, by using electrogenerated radical anions as the donors, and (iii) intramolecularly, by using purposely synthesized donor-spacer-acceptor (D-Sp-A) systems (tert-Bu 1,3-dihydro-α,α-di-Methyl-1,3-dioxo-peroxy-2H-isoindole-2-acetate and tert-Bu cis-4-Phthalimidocyclohexanepercarboxylate). Convolution anal. of the heterogeneous data led to results in excellent agreement with the dissociative electron transfer theory. The homogeneous redox catalysis data also confirmed the reduction mechanism. The cyclic voltammetries of the D-Sp-A mols. could be simulated, leading to determination of the corresponding intramol. dissociative rate constants Anal. of the results showed that, regardless of the way by which the acceptor is reduced, the investigated dissociative electron transfers are strongly nonadiabatic and, particularly, that the exptl. rates are several orders of magnitude smaller than the adiabatic limit. A possible mechanism responsible for the observed behavior is discussed.

Alkyl and aryl azides were prepared from the corresponding primary alkyl and aryl amines by reaction with fluorosulfonyl azide generated in situ from a fluorosulfonylimidazolium triflate and sodium azide, expanding access to azides and both to the 1,2,3-triazoles derived from them and to functional screens employing them. The method allowed the preparation of a library of >1000 azides from the corresponding amines; the azide library underwent copper-catalyzed azide-alkyne cycloaddition reactions to yield a library of >1000 1,2,3-triazoles.

Gonzalez-Tejera, M. J.; Garcia, M. V.; Sanchez de la Blanca, E.; Redondo, M. I.; Raso, M.

Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:616-43-3) through the article.

Electrochem. copolymerization of 3-methylpyrrole and N-methylpyrrole perchlorate doped was carried out at 2 overpotentials and at different electrodeposition times in MeCN medium. A mixture of instantaneous and progressive nucleation mechanisms was established from the c.d.-time transients. Doping/dedoping reversibility is deduced from the electrochem. study of copolymer films by cyclic voltammetry. FTIR spectrum anal. shows that electropolymerization time has a great influence on the random monomers proportion in the copolymer obtained. Although the copolymer conductivity is in the range of that measured for poly(3-methylpyrrole) and poly(N-methylpyrrole) obtained in similar conditions, it remains conductive for a much longer time than the homopolymers.

(Bu4N)2[Cu(dcdmp)2], Bu4N[Cu(dcdmp)2] and [FeCp*2]2[Cu(dcdmp)2] (H2dcdmp = 2,3-dicyano-5,6-dimercaptopyrazine; Cp* = decamethylferrocenium) were obtained and characterized. (Bu4N)2Cu(Hdcdmp)2 crystallizes in the triclinic system, space group P1̅, Z = 1, with a 9.9512(6), b 10.541(1), c 13.221(1) Å, α 69.756(9), β 88.112(6) and γ 79.658(7)°. Its crystal structure consists of layers of well isolated square planar Cu(dcdmp)22- anions alternating with layers of Bu4N+ cations along b + c, and the magnetic properties in the range 2-300 K are close to those of an ideal paramagnet with an effective magnetic moment of 1.7 μB/f.u. Bu4N[Cu(dcdmp)2] crystallizes in the monoclinic space group C2/c, Z = 8, with a 35.281(4), b 9.501(1), c 21.885(2) Å and β 109.842(9)°, being isostructural with the Au analog previously described. [Fe(Cp*)2]2[Cu(dcdmp)2] crystallizes in the monoclinic system, space group C2/c, Z = 4, with a 15.891(1), b 10.5133(7), c 30.264(3) Å and β 91.105(2)°.

The magnetic properties, due to both cation and anion S = 1/2 contributions, show a large anisotropy, ascribed essentially to the g-factor anisotropy of the Fe(Cp*)2cations.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 616-43-3, is researched, SMILESS is CC1=CNC=C1, Molecular C5H7NJournal, ACS Sustainable Chemistry & Engineering called Renewable N-Heterocycles Production by Thermocatalytic Conversion and Ammonization of Biomass over ZSM-5, Author is Xu, Lujiang; Yao, Qian; Deng, Jin; Han, Zheng; Zhang, Ying; Fu, Yao; Huber, George W.; Guo, Qingxiang, the main research direction is cellulose biomass thermocatalytic conversion ammonization heterocycle production.Category: chiral-oxygen-ligands.

Chem. conversion of biomass to value-added products provides a sustainable alternative to the current chem. industry that is predominantly dependent on fossil fuels. N-Heterocycles, including pyrroles, pyridines, and indoles, etc., are the most abundant and important classes of heterocycles in nature and widely applied as pharmaceuticals, agrochems., dyes, and other functional materials. However, all starting materials for the synthesis of N-heterocycles currently are derived from crude oil through complex multi-step-processes and sometimes result in environmental problems. In this study, we show that N-heterocycles can be directly produced from biomass (including cellulose, lignocelluloses, sugars, starch, and chitosan) over com. zeolites via a thermocatalytic conversion and ammonization process (TCC-A). All desired reactions occur in one single-step reactor within seconds. The production of pyrroles, pyridines, or indoles can be simply tuned by changing the reaction conditions. Meanwhile, N-containing biochar can be obtained as a valuable coproduct. We also outline the chem. for the conversion of biomass into heterocycle mols. by the addition of ammonia into pyrolysis reactors demonstrating how industrial chems. could be produced from renewable biomass resources. Only minimal biomass pretreatment is required for the TCC-A approach.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:56413-95-7) here.

Unsym. tetrapyrazinoporphyrazines (TPyzPzs) from the group of azaphthalocyanines with one peripherally attached amino substituent (donor) were synthesized, and their photophys. properties (fluorescence quantum yield and singlet oxygen quantum yield) were determined The synthesized TPyzPzs were expected to undergo intramol. charge transfer (ICT) as the main pathway for deactivating their excited states. Several structural factors play a critical role in ICT efficiency. The substituent in the ortho position to the donor center significantly influences the ICT, with tert-butylsulfanyl and butoxy substituents inducing the strongest ICTs, whereas chloro, Me, Ph, and hydrogen substituents in this position reduce the efficiency. The strength of the donor pos. influences the ICT efficiency and correlates well with the oxidation potential of the amines used as the substituents on the TPyzPz as follows: n-butylamine < N,N-diethylamine < aniline < phenothiazine. The ICT (with conjugated donors and acceptors) in the TPyzPz also proved to be much stronger than a photoinduced electron transfer in which the donor and the acceptor are connected through an aliphatic linker.
