Four-component synthesis of 9h-pyrimido[4,5-b]indoles using ammonium iodide as the nitrogen source

HIGHLIGHTS

• who: Yufeng Chen et al. from the Xiangtan University, Xiangtan, China have published the Article: Four-Component Synthesis of 9H-Pyrimido[4,5-b]indoles Using Ammonium Iodide as the Nitrogen Source, in the Journal: Catalysts 2023, 623 of 20/02/2023
• how: In 2020 the authors developed a base-promoted aerobic oxidation approach for the synthesis of benzimidaz -135-triazines involving 2-aminobenzimidazoles aromatic aldehydes and ammonium iodide .
