    Solution-phase parallel synthesis of new 2H-pyrimido-[4,5-e][1,2,4]triazin-3-ylidenecyanamides
    摘要:
    A practical synthesis of 2H-pyrimido[4,5-e][1,2,4]triazin-3-ylidenecyanamides has been developed. The key step is the coupling reaction of an aryldiazonium salt with 1-cyano-3-(2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-ylamino)-2-methylisothiourea followed by intramolecular cyclization. A library of 2H-pyrimido[4,5-e][1,2,4]triazin-3-ylidenecyanamides was prepared in two steps from 6-aminouracils using this method. (C) 2004 Elsevier Ltd. All rights reserved.

  • Selective <i>N</i> -Monoalkylation of 6-Aminouracils with Alcohols: An Environmentally Benign Protocol for the Synthesis of 6-Alkylaminouracils
    作者:Anggi Eka Putra、Yohei Oe、Tetsuo Ohta
    DOI:10.1002/ejoc.201701445
    日期:2018.1.23
    A highly selective N‐monoalkylation of 6‐aminouracils with alcohols was achieved through the borrowing hydrogen approach using iridium catalysis. This reaction provides an efficient and green approach to the synthesis of 6‐alkylaminouracils, which are useful intermediates in organic synthesis.

    日期:2006.5
    substituted/-unsubstituted barbituric acids with various alkyl dihalides under phase transfer catalytic conditions using DMF-K2CO3 (base), TBAHSO4 (catalyst) provide spirobarbituric acids in moderate to high yields. Irrespective of the existence of C5-monoalkylated compounds in the enolic form (confirmed by the isolation of some of its analogues), the second alkylation predominantly takes place at C5. The underlying
