Azaindole can be regarded as the biological isostere of indole, and the molecular unit of indole plays a huge role in the life process. Many drug molecules contain indole units. Azaindole is an important heterocyclic intermediate with good biological and medicinal value, and is the core structure of many drugs, such as antitumor drugs, dopamine D4 receptors, kinase inhibitors, thrombin inhibitors, etc. Therefore, it has a wide range of application value in medical research.

Indoline is an aromatic heterocyclic organic compound with the chemical formula C8H9N. The compound is based on the indole structure, but the 2-3 bond is saturated. Indoles and their derivatives continue to inspire the development of synthetic organic chemistry even years after their discovery. The specific scaffold is a privileged structure and is ubiquitous in pharmaceuticals and biologically active compounds. Fused indolines as indole derivatives are of particular interest as they are often found in natural products and bioactives such as strychnine and tryptanthrins (alkaloids), mitosanes and mitosenes (antitumor activity) and isatisine (antiviral activity).
