  • One-Pot Synthesis of<i>N</i>,<i>N</i>,<i>N</i>′,<i>N</i>′-Tetrasubstituted Ureas and Oxomalonamides by Oxidative Carbonylation of Lithium Amides at Atmospheric Pressure
    作者:Norma S. Nudelman、Elizabeth S. Lewkowicz、Daniel G. Pérez
    DOI:10.1055/s-1990-27053
    日期:——
    N,N,N′,N′-tetrasubstituted ureas have been obtained in good yields by reaction of lithium aliphatic amides in tetrahydrofuran solution with carbon monoxide under mild conditions (0°C, 1013 mbar) followed by treatment with oxygen prior to work up. N,N,N′,N′- tetrasubstituted oxomalonamides (oxopropanediamides) can be obtained under similar reaction conditions by carrying out the reaction in the presence of known amounts of the pure amine. Besides being an useful synthetic method, the present studies afford new evidence of the mechanism of the reaction.
    在温和的条件下(0°C,1013 毫巴),脂肪族酰胺四氢呋喃溶液中与一氧化碳反应,然后在升温前用氧气处理,可以得到 N,N,N′,N′- 四代。在类似的反应条件下,在已知量的纯胺存在下进行反应,可以得到 N,N,N′,N′-四取代氧代丙二酰胺(oxopropanediamides)。 除了是一种有用的合成方法外,本研究还为该反应的机理提供了新的证据。
