    摘要:
    1-苄基酸(7)的酸或碱催化酰化作用以低产率提供了7-取代衍生物9、10和11。尽管锂化7与亲电试剂的反应产生了2-取代的衍生物14、15、17、20、21和22,但将1-苄基7-溴-2-氯代锂(23)锂化,然后用Me2CHCH2CHO(13)处理)成功地在7位引入侧链,得到1-苄基-2-氯-7-(1-羟基-3-甲基丁基)(24)。用3-溴-2-丁酮将1-苄基-3-甲基鸟嘌呤(5)环化,然后进行催化氢解,得到7-甲基wye(2b),这是从古细菌转移核糖核酸分离出的高修饰碱基。通过一系列反应,开发了一种更有效的2b合成途径:7的Vilsmeier-Haack反应,用NaBH4还原以及在Pd-C上进行催化氢解。

    New Reactions of Phosgene with Tertiary Amines
    摘要:
    1-Benzylwye (3) underwent substitution at the 7-position in the presence of COCl2 and pyridine in THF to afford various products depending upon the post-treatment through 1,4-dihydropyridine (7) and carboxylic acid derivative (8). When Et3N was used instead of pyridine, it reacted with COCl2 to provide two enamines (18 and 19), together with diethylcarbamyl chloride (20), after treatment of the reaction mixture with MeOH.

  • Isomerization through Cleavage and Recombination of Imidazolide Linkage in the Condensed Tricyclic System Related to Hypermodified Bases of Phenylalanine Transfer Ribonucleic Acids.

    1-Benzyl-4, 6-dimethyl-4, 9-dihydro-1H-imidazo[1, 2-α]purin-9-one bearing an alkyl, a 1-alkenyl, a hydroxymethyl, a methoxymethyl, or a formyl group at the 7-position (3a-e) underwent rearrangement through fission and recyclization of the pyrimidine ring, attaining equilibrium with the corresponding positional isomer 4a-e in MeONa-MeOH at 25°C, whereas 7-methoxycarbonyl and 7-halogeno compounds 3f-i were irreversibly converted into the rearranged products 4f-i under identical conditions. The position of equilibrium appears to be affected by the electronic factor of the substitutent rather than the steric one. The pseudo-first-order rate constants measured for the reactions of 3a, b, d, f-i suggest that the reaction is accelerated by the electron-withdrawing substituent. However, the reactions of this series of compounds do not always obey the Hammett equation.On the other hand, a linear free energy relationship (ρ=+3.2) was observed for the rates of rearrangement of a 6-demethyl series of compounds 9a, b, d, f, g, when σ0P values were employed. The deviations from this relationship for the reactions with the 7-hydroxymethyl compound 9c and the 7-carbamoyl compound 9e are explicable in terms of the accelerative effect through intramolecular hydrogen bonding with the carbonyl oxygen at the 9-position.
    1-苄基-4, 6-二甲基-4, 9-脱氢-1H-咪唑[1, 2-α]嘌呤-9-酮在7位具有烷基、1-烯基、羟甲基、甲氧基甲基或甲酰基的化合物(3a-e)通过嘧啶环的裂解和重环化发生重排,在25°C下在MeONa-MeOH中达到与相应位置异构体4a-e的平衡,而7-甲氧基羧基和7-卤代化合物3f-i在相同条件下被不可逆地转化为重排产物4f-i。平衡位置似乎受到取代基电子因素的影响,而非空间因素。对化合物3a、b、d、f-i反应测得的伪一级速率常数表明,该反应因电子吸引取代基而加速。然而,这一系列化合物的反应并不总是遵循Hammett方程。另一方面,对于6-去甲基类化合物9a、b、d、f、g的重排速率,采用σ0P值时观察到线性自由能关系(ρ=+3.2)。对于与7-羟甲基化合物9c和7-基甲酰化合物9e的反应,这一关系的偏离可以通过与9位羰基氧的分子内氢键相互作用的加速效应来解释。
