    [reaction: see text] The first examples of C(6)-substituted 7-hydroxy-6,7-dihydro-5H-imidazo[1,2-b][1,2,4]triazines have been prepared by ring closure of different 5(2H)-1,2,4-triazin-3-ones 1a-c with 40% aqueous glyoxal and various nucleophiles (alcohols, thiols, or amines). The structure and exact stereochemistry of 2a was established by a single X-ray diffraction study and (1)H and (13)C NMR spectra

  • Aromatization and ring cyclization: A better understanding on the ring cyclization mechanism of 3-amino-6-hydrazino-1,2,4-triazin-5(2<i>H</i>)-one reacted with acetic acid in<i>N,N</i>-dimethylformamide

    ,2,4-triazin-5(2H)-one (7) is formed. Single-crystal X-ray analysis of a 3-ethyl derivative of compound 1 reveals the predominant tautomeric structure to be the 7H-tautomer (7H-1). From these results, we propose a reasonable cyclization mechanism that incorporates two important points: (1) the tautomerism of the N-2 hydrogen with the C-5 oxo group aromatizes the 1,2,4-triazine ring, and (2) the DMF
    在本文中,我们报告标题化合物(3)与过量的N,N-二甲基甲酰胺(DMF )反应,该溶液含有两当量的乙酸,得到6-氨基-1,2,4-三唑[3,4- f ] [ 1,2,4]三嗪-8(7 H)-一(1)。当3-氨基-2-苄基-6-肼基-1,2,4-三嗪-5(2 H)-一(6)时,在相同条件下处理3的N-2苄基化衍生物,环环化不会发生 相反,形成3-氨基-2-苄基-6-(2-甲酰基-肼基)-1,2,4-三嗪-5(2H)-一(7)。化合物1的3-乙基衍生物的单晶X射线分析揭示了主要的互变异构结构为7 H-互变异构体(7 H - 1)。根据这些结果,我们提出了一个合理的环化机制,该机制包括两个要点:(1)N-2氢与C-5氧代基团的互变异构使1,2,4-三嗪环芳构化,以及(2) DMF由乙酸在氮原子上质子化,然后在DMF被3或6的6-肼基攻击时发生脱氨作用。

    The AstraZeneca approach to synthetic Route Design is exemplified through our AZD4635 chemical development program. The identification of possible new route concepts is presented, as well as their subsequent prioritization for practical exploration based on project objectives. Selected ideas were tested to demonstrate proof of concept for the bond formation strategy and, where successful, were fed into a decision tool based on key SELECTion principles.
  • Synthesis and Structure Assignment of 1-(2-Acetoxyethoxy)methyl Derivatives of 5-Chloro-6-azauracil and 5-Bromo-6-azaisocytosine

    1-[(2-Acetoxyethoxy)methyl]-5-chloro-6-azauracil has been prepared and its unambiguous assignment of H-1 and C-13 peaks through the H-1-C-13 heteronuclear correlation (HETCOR) NMR experiments is described. The isosteric 1-[(2- acetoxyethoxy)methyl]-5-bromo-6-azaisocytosine has also been synthesized. The X-Ray crystallographic analysis reveals unambiguously the site of glycosylation at N-1 Deacetylation of both acyclonucleosides provided 5-chloro-1-[(2-hydroxyethoxy)methyl]6-azauracil and 5-bromo-1-[(2-hydroxyethoxy)methyl]-6-azaisocytosine respectively. Their structures have been well established by the NMR spectra and the elemental analyses.
