  • Synthesis of urea derivatives from amines and CO2 in the absence of catalyst and solvent
    作者:Chaoyong Wu、Haiyang Cheng、Ruixia Liu、Qiang Wang、Yufen Hao、Yancun Yu、Fengyu Zhao
    DOI:10.1039/c0gc00059k
    日期:——
    Urea derivatives are obtained in mild to good yield from the reactions of primary aliphatic amines with CO2 in the absence of any catalysts, organic solvents or other additives. To optimize reaction conditions, experimental variables including temperature, pressure, the concentration of amine, reaction time etc. were studied. Satisfactory yields were obtained at the optimized conditions that are comparable

    DOI:10.1021/jo0494634
    日期:2004.7.1
    A general synthesis of symmetrically disubstituted ureas and trisubstituted ureas by direct Pd-catalyzed oxidative carbonylation of primary amines or of a mixture of a primary and a secondary amine, respectively, with unprecedented catalytic efficiencies for this kind of process, is reported. Reactions are carried out at 90−100 °C in DME as the solvent in the presence of PdI2 in conjunction with an
    据报道,通过直接钯催化的伯胺或伯胺和仲胺混合物的直接羰基氧化羰基化,一般合成对称的二取代的脲和三取代的脲,对于这种方法具有空前的催化效率。反应在90-100°C的DME中作为溶剂,在PdI 2的存在下,与过量的KI作为催化体系,在20 atm的CO和空气的4:1混合物下进行。在某些情况下,在过量CO 2的存在下工作除CO和空气(总共60个大气压)外(40个大气压)对底物反应性和产物收率有有益的影响。环状五元和六元尿素很容易由伯二胺形成。该方法已成功地用于合成具有药理活性的尿素,例如那些衍生自α-氨基酯或尿素NPY5RA-972(神经肽Y5受体的强效拮抗剂)的尿素。
  • A novel and efficient method for the Pd-catalysed oxidative carbonylation of amines to symmetrically and unsymmetrically substituted ureas

    DOI:10.1039/b211740a
    日期:2003.2.7
    A new method for the Pd-catalysed oxidative carbonylation of amines to symmetrically and unsymmetrically substituted ureas with unprecedented catalytic efficiencies for this kind of reaction has been developed.

  • Conversion of carbonimidodithioates into unsymmetrical Di- and Tri- substituted ureas including urea dipeptides
    作者:Mariappan Anbazhagan、Abdul Rakeeb A.S. Deshmukh、Srinivasachari Rajappa
    DOI:10.1016/s0040-4039(98)00561-9
    日期:1998.5
    Selective hydrolysis of carbonimidodithioates (3) leads to the thiocarbamates (4), which can be easily transformed to the unsymmetrical ureas (5) by treatment with the appropriate amines. This constitutes a synthesis of ureas without the use of phosgene or carbon monoxide.
    碳亚氨基二硫代碳酸酯(3)的选择性水解会生成硫代氨基甲酸酯(4),通过用适当的胺处理,硫代氨基甲酸酯(4)可以轻松转化为不对称脲(5)。这构成了不使用光气或一氧化碳的脲的合成。
