efficient Pd/C-catalyzed carbonylation of both aliphatic and aromatic azides in the presence of amines is reported. Serving as the widely existed fragments in an array of biological pharmaceuticals, functionalized unsymmetrical ureas were straightforwardly synthesized by using readily available and cheap azides with amines under CO atmosphere, with the extrusion of N2 as the only byproduct. It was found
据报道,在胺的存在下,脂肪族和芳香族叠氮化物的Pd / C催化简便,有效地羰基化反应。作为一系列生物药物中广泛存在的片段,在CO气氛下使用易于获得的廉价胺与胺进行叠氮化,可以直接合成官能化的不对称脲,而N 2是唯一的副产物。发现不仅芳基叠氮化物而且苄基和烷基叠氮化物也适用于该方法。该程序的另一个特点是采用了高效的钯木炭催化系统。
