  • <i>N</i>-(<i>tert</i>-Butyldimethylsilyl)imidazole and related heterocycles: <sup>13</sup>C nuclear magnetic resonance study and reaction with dimethylsulfoxide
    作者:Alexander F. Janzen、Gerald N. Lypka、Roderick E. Wasylishen
    DOI:10.1139/v80-010
    日期:1980.1.1

    N-tert-Butyldimethylsilyl derivatives of imidazole, 2-methylimidazole, 4-methylimidazole, benzimidazole, pyrazole, 1,2,4-triazole, and benzotriazole were prepared from tert-butyldimethylsilyl chloride and the corresponding heterocyclic compound. The products were identified by carbon and proton nmr, mass spectrometry, and elemental analysis. The carbon nmr spectra confirmed the absence of intermolecular silyl exchange at ambient temperature. Silyl exchange did occur at elevated temperatures, 130–160 °C.Reaction of N-tert-butyldimethylsilyl or N-trimethylsilyl heterocycles with dimethylsulfoxide gave N-(methylthio)methyl derivatives of imidazole, 2-methylimidazole, 4-methylimidazole, benzimidazole, pyrazole, and 1,2,4-triazole. The products were characterized by carbon and proton nmr, mass spectrometry, and elemental analysis. A mechanism involving a Pummerer rearrangement is proposed to account for the results.

    N-叔丁基二甲基硅基衍生物的咪唑、2-甲基咪唑、4-甲基咪唑、苯并咪唑、吡唑、1,2,4-三唑和苯并三唑是从叔丁基二甲基氯硅烷和相应的杂环化合物制备的。产物通过碳和质子核磁共振、质谱和元素分析进行鉴定。碳核磁共振谱图确认在常温下不存在分子间硅基交换。在升高温度(130-160°C)时,硅基交换确实发生。N-叔丁基二甲基硅基或N-三甲基硅基杂环与二甲亚砜反应,得到咪唑、2-甲基咪唑、4-甲基咪唑、苯并咪唑、吡唑和1,2,4-三唑的N-(甲硫基)甲基衍生物。产物通过碳和质子核磁共振、质谱和元素分析进行表征。提出了一种涉及Pummerer重排的机制来解释这些结果。
  • Nucleophilic activation of hydrogen peroxide. On the formation and the reactivity of 1H-1,2,4-triazoleperoxycarboxylic acid and O-p-nitrophenylmonoperoxycarbonic acid †
    作者:Carsten Bender、Hans-Dieter Brauer
    DOI:10.1039/a903852c
    日期:——
    Measurements of the infrared phosphorescence of singlet molecular oxygen (1O2) at 1270 nm have been employed to demonstrate the formation of 1O2 in the system N,N′-carbonyldi-1,2,4-triazole (CDT)–hydrogen peroxide and in the system 1H-1,2,4-triazolecarboxylic acid p-nitrophenyl ester (TCNP)–hydrogen peroxide in tetrahydrofuran. At hydrogen peroxide concentrations of [H2O2] ≥ 2 [CDT] or ≥ 2 [TCNP] one molecule of 1O2 is generated per molecule of CDT and TCNP, respectively. In both systems a very reactive peroxy-intermediate is formed. In the system CDT–H2O2 the 1H-1,2,4-triazoleperoxycarboxylic acid (1) is generated, in TCNP–H2O2 the p-nitrophenylmonoperoxycarbonic acid (4). For the epoxidation of cyclohexene in THF by 1 a rate constant k15 ≈3 × 100 dm3 mol–1 s–1 can be estimated. For 4 the corresponding rate constant was found to be k20 ≈ 6 × 10–2 dm3 mol–1 s–1. The Arrhenius parameters of the formation of 1 and 4, respectively, and in addition of their consecutive reactions with hydrogen peroxide were determined. The results are consistent with the assumption that the nucleophilic displacements by hydrogen peroxide at the carbonyl carbon atom are addition–elimination processes, which take the form of a BAC2-mechanism.
    在四氢呋喃中,通过测量单线态分子氧(1O2)在1270 nm处的红外磷光,证明了在N,N'-羰基二-1,2,4-三唑(CDT)–过氧化氢体系和1H-1,2,4-三唑羧酸对硝基苯酯(TCNP)–过氧化氢体系中1O2的生成。当过氧化氢浓度[H2O2]≥2[CDT]或≥2[TCNP]时,CDT和TCNP分子各自生成一个1O2分子。在这两个体系中,都形成了一个高度活性的过氧中间体。在CDT–H2O2体系中生成1H-1,2,4-三唑过氧羧酸(1),在TCNP–H2O2体系中生成对硝基苯单过氧碳酸(4)。对于1在THF中环己烯环氧化反应的速率常数k15≈3×100 dm3 mol−1 s−1可以估算出来。对于4,相应的速率常数被发现为k20≈6×10−2 dm3 mol−1 s−1。分别确定了1和4的形成以及它们与过氧化氢的连续反应的阿伦尼乌斯参数。结果与假设一致,即过氧化氢在羰基碳原子上的亲核取代是加成-消除过程,表现为BAC2机制。

    Novel nucleotide compounds represented by the formula (I) wherein R1 represents a protective group or a PEG bearing organic group; R2, R2′, R2″, R3, R3′ and R3″ each represents a hydrogen atom or an alkyl, cycloalkyl, aryl or aralkyl group which may contain a hetero-atom; B1, B2, B3 and B4 each represents a base, if necessary, protected by a protective group common in nucleotide chemistry or by a PEG bearing organic group; X, X′ and X″ each represents an oxygen atom or a sulfur atom; Y represents an azolyl group, a mono- or di-alkylamino group or a saturated nitrogenous heterocyclic ring; A1, A2, A3 and A4 each represents a hydrogen atom, a hydroxyl group, an alkoxy group or a trialkylsilyloxy group; and m and n each represents 0 or an integer of 1 to 100. The nucleotide of the formula (I) can be used as it is in a reaction mixture for further reaction with 3′-O- and 5′-O-unprotected nucleoside or nucleotide of the formula (II) to yield a nucleotide block or oligonucleotide, and thus is useful as in situ DNA synthesis reagents.
    根据公式(I)表示的新型核苷酸化合物: 其中R1代表保护基团或携带有机基团的聚乙二醇;R2、R2′、R2″、R3、R3′和R3″每个代表氢原子或可能含有杂原子的烷基、环烷基、芳基或芳烷基团;B1、B2、B3和B4每个代表一个碱基,如有必要,由核苷酸化学中常见的保护基团或携带有机基团的聚乙二醇保护;X、X′和X″每个代表氧原子或硫原子;Y代表唑基团、单烷基或二烷基氨基团或饱和氮杂环;A1、A2、A3和A4每个代表氢原子、羟基、烷氧基或三烷基硅氧基;m和n每个代表0或1到100的整数。公式(I)的核苷酸可以以其本身的形式用于反应混合物中,与3′-O-和5′-O-未保护的公式(II)的核苷或核苷酸进一步反应,产生核苷酸块或寡核苷酸,因此作为原位DNA合成试剂非常有用。
  • A Novel, Simple Cyclocondensation Reaction Towards Glycosyl Triazines

    Sugars bearing an isothiocyanate moiety at C-1 react with diazadienium iodide to afford glycosyl triazines that represent, through an easy cyclocondensation reaction step, a flexible entry to different nucleoside analogues. We herein demonstrate that this [4+2] cycloaddition reaction occurs with total regiocontrol and good yields. Subsequent transformation of the thiocarbonyl into a carbonyl, and nucleophilic substitution of the methylsulfanyl group by ammonia, yields the 5-azacytidine analogues. All compounds were fully characterised by IR, HRMS, and ¹³C and ¹H NMR (COSY­, HMBC and HMQC).
    在C-1位带有异硫氰酸基团的糖与二氮二烯丙碘反应生成糖基三嗪类化合物,这些化合物通过一步简单的环加成反应,提供了一种灵活的途径来制备不同的核苷类似物。我们在此证明,这种[4+2]环加成反应具有完全的区域选择性和良好的产率。随后将硫羰基转化为羰基,并通过氨对甲硫基进行亲核取代,得到了5-氮胞苷类似物。所有化合物均通过IR、HRMS以及¹³C和¹H NMR(包括COSY、HMBC和HMQC)进行了全面的表征。
