Safety of 1-Iodo-2-methylbutane. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Kinetics, products and mechanism of O(3P) atom reactions with alkyl iodides.

Alkyl halides are an important source of halogens in the atm. In the case of alkyl iodides, relative kinetic studies of their OH reactions in photoreactors are complicated by fast reactions with the O(3P) atoms generated by the photochem. OH radical sources. In the present study, the relative kinetic technique was applied in large and small photoreactors to measure rate coefficients for the reaction of O(3P) atoms with a series of alkyl iodides at room temperature and atm. pressure. The products formed in N2 were also investigated. Alkenes and HOI are the major products of the reactions and the alkene was quantified for the majority of the alkyl iodides studied.

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).Product Details of 616-14-8. 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.

Application of 616-14-8. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Hydrophobic Pocket Occupation Design of Difluoro-Biphenyl-Diarylpyrimidines as Non-Nucleoside HIV-1 Reverse Transcriptase Inhibitors: from N-Alkylation to Methyl Hopping on the Pyrimidine Ring. Author is Ding, Li; Pannecouque, Christophe; De Clercq, Erik; Zhuang, Chunlin; Chen, Fen-Er.

Considering the nonideal metabolic stability of the difluoro-biphenyl-diarylpyrimidine lead compound I, a series of novel alkylated difluoro-biphenyl-diarylpyrimidines were designed and synthesized based on their structure. Introducing alkyl or substituted alkyl groups on the linker region to block the potential metabolic sensitive sites generated 22 derivatives Among them, compound II with an N-Me group displayed excellent anti-HIV-1 activity and selectivity. The Me group was hopped to the central pyrimidine to occupy the small linker region and maintain the water-mediated hydrogen bond observed in the binding of compound I with RT. The resulting compound III exhibited an improved anti-HIV-1 activity, much lower cytotoxicity, and nanomolar activity toward multiple mutants. In addition, III has a better stability in human liver microsomes than I. Moreover, no apparent in vivo acute toxicity was observed in III-treated female, especially pregnant mice. This series of alkylated compounds with highly potency and safety represent a promising lead template for future discovery.

Synthesis and evaluation of mammary tumor inhibiting activity of 3-alkylated 3-(4-aminophenyl)piperidine-2,6-diones. Author is Hartmann, Rolf W.; Batzl, Christine.

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.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Asymmetric reductions. VI. The action of the Grignard reagent from (+)-1-chloro-2-methylbutane on a series of alkyl tert-butyl ketones》. Authors are Foley, William M.; Welch, Frank J.; Combe, Edward M. La; Mosher, Harry S..The article about the compound:1-Iodo-2-methylbutanecas:616-14-8,SMILESS:CCC(CI)C).Product Details of 616-14-8. Through the article, more information about this compound (cas:616-14-8) is conveyed.

cf. C.A. 51, 1828h. Title reactions were carried out with six ketones, and the % asymmetric reduction, i, was determined by comparing the observed rotation of each resulting carbinol with the maximum rotation of pure isomers obtained by resolution. The absolute configurations of the prepared carbinols were determined and R, [α]25D (neat), and i were as follows: Me, 0.63°, 13.4; iso-Pr, -0.38°, 4.6; Et, -2.94°, 10.7; Pr, -3.87°, 11.3; Bu, -3.78°, 11.0; and iso-Bu, -2.56°, 5.9. The results agreed with a reaction mechanism of Grignard reduction involving an intermediate cyclic six-membered transition state in which stereospecificity was controlled by steric interaction of the alkyl and tert-butyl groups of the ketones and the Me and Et groups of the Grignard reagent. The alkyl tert-butyl ketones were prepared by coupling the appropriate acid chloride, RCOCl, with the Grignard reagent from freshly distilled tert-BuCl in the presence of Cu2Cl2 to yield the following products (R, % yield based on Grignard reagent, b.p., and n25D given): Me, 33, 105.2°, 1.3974; Et, 89, 125.0-5.8°, 1.4049-51; Pr, 63, 145.0-5.8°, 1.4109-11; iso-Pr, 36, 135.2-6.7°, 1.4049-68; Bu, 69, 167.0-9.0°, 1.4149-59; and iso-Bu, 40, 155.5-7.0°, 1.4135-42. Only the Me and Pr tert-butylcarbinols were resolved in earlier work, and the resolution of the remaining four, by classical methods (Ingersoll, C.A. 38, 29257), is reported here. Racemic tert-BuCHEtOH (I), b. 136°, n20D 1.4235, was converted to the dl-acid phthalate, m. 88.0-8.3°. By procedures involving brucine and recrystallizations the (-)-acid phthalate (II) was obtained, m. 91.0-1.5°, [α]27D -3.75° (c 20.5, CHCl3), the rotation in CHCl3 being concentration dependent, 2.2° (c 1.5). (+)-I was regenerated from II, n20D 1.4230, α23D 27.40° (neat, l 1); acetate from (+)-I b38 74°, α24D 12.16° (neat, l 0.5), d23 0.856; benzoate from (-)-I b0.8 20°, α25D -3.19° (neat, l 0.5), n20D 1.4912, d23 0.957. Racemic tert-BuCH(OH)Pr-iso (III), b. 150.9-1.1°, n20D 1.4290-9, gave the dl-acid phthalate, m. 114.5-16.0°. The brucine salt was prepared and a less soluble form obtained, m. 173-5°, [α]28D -23°, which on hydrolysis gave an acid phthalate (IV), m. 100.5-3.0°, [α]25D 0.00°, which was hydrolyzed to (-)-III, α28D -7.22° (neat, l 1). Hydrolysis of the more soluble form of the brucine salt, [α]28D -16.1°, gave an acid phthalate (V), [α]28D 0.00°, which on hydrolysis gave (+)-III, α28D 7.22° (neat, l 1). The strychnine salt of IV was also prepared, [α]28D -25.7°, the acid phthalate regenerated, and converted to (-)-III, α28D -8.94° (neat, l 1), n20D 1.4300. The cinchonine salt of V was prepared, m. 144-7° (decomposition), [α]28D 106°, from which an acid phthalate was regenerated, m. 105.5-7.0°, and hydrolyzed to (+)-III, α28D 9.06° (neat, l 1). These latter values of -8.94° for (-)-III and 9.06° for (+)-III were considered best values. Also prepared were acetate of (+)-III, b155 130°, n21D 1.4166, α28D -1.44° (neat, l 1), and benzoate of (+)-III, b32 195°, n19D 1.4969, α25D -0.16° (neat, l 1). Racemic tert-BuCH(OH)Bu-iso (VI), b150 115-16°, n25D 1.4309, m. 17°, gave acid phthalate (VII), m. 83.5-4.5°. Strychnine was used in the resolution and eventually (+)-VII was obtained, m. 75.6-7.5°, [α]23D 8.7° (c 1.5, CHCl3), hydrolyzed to (+)-VI, m. 40-1°, α26D 57.5° (c 20.4, MeOH), and α23D 54.5° (neat, by extrapolation of rotation-concentration curve); acetate of (+)-VI b17 73°, α22D 15.15° (neat, l 0.5), n20D 1.4176, d22 0.852; benzoate of (+)-VI b0.6 88°, α25D 8.24° (neat, l 0.5), n20D 1.4870, d25 0.955. Racemic tert-BuCHBuOH (VIII), n20D 1.4320, was converted to acid phthalate (IX), m. 100.5-2.0°, and then to the strychnine salt. The regenerated (+)-IX was a glass, α23D 4.5° (c 2.8, CHCl3), which was saponified to (+)-VIII, n20D 1.4314, α24D 17.10° (neat, l 0.5). The (-)-phthalate from the more soluble fractions of strychnine salt gave (-)-VIII, α24D -16.39° (neat, l 0.5). The dl-tetrachlorophthalate of VIII was also prepared, m. 126-8°, converted to the strychnine salt, and the less soluble form, [α]25D -12°, hydrolyzed to (-)-acid tetrachlorophthalate, α22D -9.69°, which was saponified to (+)-VIII, α22D 13.70° (neat, l 0.5); 3,5-dinitrobenzoate (X) of (+)-VIII m. 107.5° (MeOH), α25D 10.0° (c 2.4, CHCl3); 3,5-dinitrobcnzoate of dl-VIII, m. 84.0-4.5°. X was saponified to (+)-VIII, b23 76°, α25D 17.12° (neat, l 0.5), n20D 1.4310, d26 0.823. The value for pure (+)-VIII was taken as α25D 34.24° (neat, l 1). From (-)-VIII, α25D -32.8° (neat, l 1), was prepared: acetate, b20 87°, α26D -11.25° (neat, l 0.5), n20D 1.4191, d26 0.851; benzoate, b0.5 98°, α25D -7.29° (neat, l 0.5), n20D 1.4887, d25 0.936; p-nitrobenzoate, b0.5 144-5°, α29D -12.50°, n25D 1.5070.

Sorption of MeBr on groundnuts (I) was studied with both undecorticated I and I separated into husk, cotyledon, and germ. Successful treatment of I with MeBr depended on the moisture content of the nuts. Impairment of germination following MeBr treatment was observed when the moisture content exceeded 5%. Sorption of MeBr was found to increase more rapidly than the dosage, necessitating careful dosage control. At concentrations lower than that critical for a particular moisture content and period of fumigation, a slight stimulating action of MeBr on germination was observed.
