A ruthenium-catalysed arene ortho C–H amidation of 4-aryl-pyrrolo[2,3-d]pyrimidinederivatives with acyl azides or phosphoryl azides as the nitrogen sources toward C–N bond formation was developed. This protocol could offer a novel and direct approach to access a series of amidated and phosphoramidated pyrrolo[2,3-d]pyrimidinederivatives in moderate to good yields, thereby evading the general Curtius
开发了钌催化的 4-芳基吡咯并[2,3- d ]嘧啶衍生物与酰基叠氮化物或磷酰叠氮化物作为氮源形成 C-N 键的芳烃邻位C-H 酰胺化反应。该方案可以提供一种新颖且直接的方法,以中等至良好的产率获得一系列酰胺化和磷酰胺化吡咯并[2,3 -d ]嘧啶衍生物,从而避免一般的Curtius重排。该方案具有显着的官能团耐受性和单步过程,仅释放无害的分子氮作为副产物。

A set of 20 2-cyanoaziridine-1-carboxamides was synthesized from 2-cyanoaziridine and appropriate isocyanates. These compounds were active against a variety of solid and hematological tumor cells in culture, including strains resistant to doxorubicin and mitoxantrone. Their potencies in these assays correlated with the lipophilicity of substituents. The N-phenyl derivative was more potent and equally effective to imexon, a cyclized 2-cyanoaziridine-1-carboxamide of clinical interest, against cloned fresh human tumors.
