Compound: 1-Methyl-4-nitro-1H-imidazol-5-amine, is researched, Molecular C4H6N4O2, CAS is 4531-54-8, about A catalyst and additive-free three-component reaction of highly electrophilic azides with cyclic ketones and cycloaliphatic amines. Synthesis of novel N-heteroaryl amidines.Name: 1-Methyl-4-nitro-1H-imidazol-5-amine.

Highly electrophilic 5-azido-1-methyl-4-nitro-1H-imidazole and sulfonyl azides were demonstrated to react with alicyclic amines and cyclic ketones in the absence of any catalyst or additive to afford novel N-(4-nitroimidazol-5-yl)- or N-sulfonylamidines resp. Based on single crystal X-ray anal., a revision of the previously reported data of Gao and co-workers on the direction of the reaction of sulfonyl azides with endocyclic enamines was made. The reaction of 2,6-diazidopyridine with an enamine, 4-(cyclohex-1-en-1-yl)morpholine, proceeded with cyclization of the azide moiety onto the pyridine C=N bond to form an amidine bearing the tetrazolo[1,5-a]pyridine fragment.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Secondary to normal alkyl group rearrangements in octahedral iridium(III) complexes. 1. Monoalkyl derivatives, the main research direction is alkyl group isomerization iridium complex; solvent effect alkyl isomerization; substituent effect alkyl isomerization; steric hindrance alkyl isomerization.HPLC of Formula: 616-14-8.

sec-Alkyliridium(III) complexes IrYIR(CO)L2 (R = sec-alkyl; Y = Cl, I; L = PMe3, PMe2Ph), formed by oxidative addition of sec-alkyl iodides to IrY(CO)L2, rearrange cleanly by a first-order process to the n-alkyl isomers on dissolution in CH2Cl2 containing protic solvents. The order of efficacy of these solvents in promoting alkyl group rearrangement is CF3CO2H >> CH3OH >> C2H5OH > CH3CO2H ∼ PrOH > (CH3)2CHOH, while in the more strongly coordinating medium of THF the order is H2O >> CH3OH. These orders correlate with the anion-solvating ability of the solvents and, together with the observed retardation by added iodide ion, suggest that the rate-determining step in the rearrangement is dissociation of iodide ion trans to the sec-alkyl group. Rapid, reversible β-hydride elimination in the resulting cation and stereospecific return of iodide ion trans to the resulting n-alkyl group complete the process. The rearrangement is promoted by increasing bulk, both of the alkyl group, up to a certain limit, and of the tertiary phosphine (PMe2Ph > PMe3). Treatment of IrClI{CH(CH3)2}(CO)(PMe2Ph)2 with AgBF4 in MeCN induces immediate alkyl group rearrangement to give the n-propyliridium(III) salt [IrClPr(CO)(NCMe)(PMe2Ph)2]BF4. Studies of analogous CD2CH3 compounds suggest that they, and presumably other n-alkyliridium(III) complexes, undergo reversible β-hydride elimination more slowly than the sec-alkyl complexes. The D labels in the isobutyl-d2 complex IrClI{CD2CH(CH3)2}(CO)(PMe3)2 scramble over all the alkyl C atoms when the compound is heated in CD2Cl2/CD3OD, indicating that a tert-butyliridium(III) species is accessible. Surprisingly, the complexes IrClI{CH2CH(CH3)CH2CH3}(CO)(PMe3)2 and IrClI{CH2CH2CH(CH3)2}(CO)(PMe3)2 do not interconvert under the same conditions, implying that a tert-pentylirdium(III) species cannot be formed. The results are compared with alkyl group rearrangements that occur in other transition-metal systems, especially those promoted by dissociation of Ph3P in (η-C5H5)FeR(CO)(PPh3).

Piperidinediones I (R = H, Me, Et, Pr, CHMe2, CH2CHMe2, CHMeEt, pentyl, isopentyl, CH2CHMeEt, sec-pentyl, hexyl, heptyl) were prepared by alkylating PhCH2CN, addition reaction of PhCHRCN with CH2:CHCN, hydrolysis and ring closure of NCCRPhCH2CH2CN, nitration, and reduction of the nitro group. In vitro I showed a stronger inhibition of human placental aromatase than aminoglutethimide (II). The most active derivative, I (R = isopentyl), showed a 93-fold stronger inhibition than II. I, except I (R = CHMe2, CH2CHMe2, CHMeEt) exhibited equal or lower inhibition of bovine adrenal desmolase than II. Many I showed a stronger inhibition of the plasma estradiol concentration of pregnant mare serum gonadotropin-primed rats than II. They inhibited the testosterone-stimulated tumor growth of ovariectomized 9,10-dimethyl-1,2-benzanthracene tumor-bearing rats more strongly than II. Being stronger and more selective inhibitors of the estrogen biosynthesis than II, some of the newly developed derivatives of II might be better candidates for the treatment of hormone-dependent human breast cancer.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Two Distinct Thermal Stabilities of DNA and Enzymatic Activities of DNase I in a Multistep Assembly with Carbazole Ligands: Different Binding Characteristics for Duplex and Quadruplex DNA.Electric Literature of C5H11I.

A partially hydrophobic carbazole ligand ((Im+)2Cz: 2,2′-(9-ethyl-9 H-carbazole-3,6-diyl)bis(ethyne-2,1-diyl)bis(1,3-dimethyl-1 H-imidazol-3-ium)) adopts two different binding states (binding states I and II) in its interactions with calf-thymus (ct-) DNA. Two distinct binding states were identified by biphasic UV/Vis and CD spectral changes during the titration of DNA into the carbazole ligand. At low concentrations of ct-DNA, (Im+)2Cz binds to nearly every part of ct-DNA (binding state I). By contrast, an increased concentration of ct-DNA results in a switch in the DNA-binding state, so that the ligands are bound per five DNA base pairs. Similarly, a monocationic carbazole ligand (Im+Cz: 2-((6-bromo-9-ethyl-9 H-carbazol-3-yl)ethynyl)-1,3-dimethyl-1 H-imidazol-3-ium) also shows biphasic UV/Vis spectral changes during the titration of ct-DNA into Im+Cz, which suggests two different binding states of the Im+Cz ligand with ct-DNA. The stepwise equilibrium of the ligand-DNA-complex formation is capable of switching the thermal stability of ct-DNA, as well as the enzymic activity of DNase (DNase I). In binding state I, the (Im+)2Cz ligands interact with nearly every base pair in ct-DNA and stabilize the double-helix structure, which results in a larger increase in the melting temperature of the ct-DNA than that observed with binding state II. On the other hand, the (Im+)2Cz ligand significantly reduces the enzymic activity of DNase I in binding state I, although the enzymic activity is recovered once the binding state of the ligand-DNA complex is changed to binding state II. The (Im+)2Cz ligand was also employed as a binder for G-quadruplex DNA. In contrast to the stepwise complex formation between (Im+)2Cz and ct-DNA, (Im+)2Cz shows a monotonous UV/Vis spectral response during the titration of G-quadruplex DNA into (Im+)2Cz, which suggests a single binding state for (Im+)2Cz with G-quadruplex DNA.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Analysis of rotatory dispersions of configurationally related halides》. Authors are Levene, P. A.; Rothen, Alexandre; Marker, R. E..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).COA of Formula: C5H11I. Through the article, more information about this compound (cas:616-14-8) is conveyed.

Rotatory dispersion curves of halides of the type HMeRC(CH2)nX (X = Cl, Br, I; R = alkyl group; n = 0, 1, 2 or 3) are analyzed in the visible and the ultraviolet regions. The 3 halogen atoms function similarly with respect to the character of this curve in compounds of identical structure. A periodicity in the sign of some of the partial contributions of the halogen atom occurs with increase in n. The course of the rotatory dispersion when n = 1 is anomalous. An attempt is made to apply results when n > 0 to the sign of rotation for compounds where n = 0. When X = COOH, CHO, CN, CHMe2, etc., no complete analogy exists between this group and the group where X is a halogen. [M]D25 maximum (homogeneous) is given for the 16 compounds where X = Br, n = 1, 2, 3, 4, and R = Et, Pr, Bu, pentyl, and for the compound HMeEtC(CH2)5Br. Absorption spectra are given for λ 2100-3300 for 5 iodides. Rotatory dispersion curves are given for the compounds HMeEtCCH2I, HMe(C6H13)CCH2I, HMeEtCCH2Br and HMeEtCCH2Cl. [M]D25 maximum, nD25, d425 (vacuum) and rotatory dispersions (numerical) are given for several other compounds in this series. Differences between the interpretation of the dispersions of the iodides given by the authors (C. A. 27, 951) and that given by Kuhn (C. A. 29, 7159.1) are due to substantial differences between their exptl. data.
