Further the design and synthesis of a quality heterocyclic compound library with N-atoms as new chemical probes active, is vital in drug discovery. In this context, an efficient one-pot multicomponent strategy for the synthesis of a mini library of 1,4-disubstituted 1,2,3-triazoles is described. This new multicomponent one-pot method features a combination of ionic liquid supported Cu(II) precatalysts
具有两个至三个氮原子的杂环化合物在细胞的正常生命周期中起着关键作用。进一步设计和合成具有N的优质杂环化合物库原子作为新的化学探针,在药物发现中至关重要。在本文中,描述了一种用于合成1,4-二取代的1,2,3-三唑的小型文库的有效的一锅多组分策略。这种新的多组分一锅法的特征在于,离子液体负载的Cu(II)预催化剂在甲醇催化的[3 + 2]-环加成反应中与微波辐射反应相结合。合成操作包括用甲醇有效还原离子液体负载的Cu(II)催化剂,然后使用原位生成的叠氮化物与炔烃进行[3 + 2]环加成反应,从而选择性地获得1,2,3-三唑。
