substrates to access new luciferin analogs. The structures of all new products were elucidated by multinuclear NMR spectroscopy and high accuracy mass spectral analysis. Crystal-structuredetermination by means of single-crystal X-ray diffraction was carried out on (4-bromophenyl)carbamoyl cyanide, 5,6-dimethoxybenzo[d]thiazole-2-carbonitrile, 5-(benzyloxy)benzo[d]oxazole-2-carbonitrile, 4,7-dimetho
氰基甲酰胺作为组装关键中间体和生物活性分子的有用成分无处不在。开发一种有效且简单的方法来处理这个主题是一个挑战。在此,我们证明了 I 2 -DMSO 氧化系统在从N制备N-芳基氰基甲酰胺中的有效性。-芳基氰基硫代甲酰胺。该合成方法具有条件温和、底物范围广、反应效率高等特点。此外,这种方法提供了一个很好的入口,可以专门提供 2-氰基苯并噻唑,它们是获得新荧光素类似物的有用底物。所有新产品的结构均通过多核核磁共振光谱和高精度质谱分析进行了阐明。用单晶X射线衍射对(4-溴苯基)氨基甲酰氰、5,6-二甲氧基苯并[ d ]噻唑-2-甲腈、5-(苄氧基)苯并[ d ]恶唑进行晶体结构测定-2-甲腈,4,7-二甲氧基苯并[ d]噻唑-2-甲腈和(5-碘-2,4-二甲氧基苯基)氨基甲酰氰,一种具有机理意义的关键中间体。
