Reference of 58755-70-7,Some common heterocyclic compound, 58755-70-7, name is 1-Iodo-4-methoxy-2-nitrobenzene, molecular formula is C7H6INO3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Arene (0.10 mmol, 1.0 equiv), Pd(OAc)2 (2.2 mg, 10 mumol,10 mol%), ligand (15 mol% or 20 mol%), hydrogen phosphate (15 mol% for benzylamine substrate), aryl iodide (0.3 mmol, 3.0 equiv.) and silver acetate (50 mg, 0.30 mmol, 3.0 equiv.) were added into a 2-dram reaction vial. Solvent and (+)-NBE-CO2Me (20 mol% or 50 mol%) were added to the mixture. The vial was flushed with N2 and capped. The reaction mixture was then stirred at the selected temperature for 12-24 h. After cooling to room temperature, the mixture was filtered through Celite and eluted with ethyl acetate. The filtrate was evaporated under reduced pressure. Purification by preparative thin-layer chromatography afforded the desired product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Iodo-4-methoxy-2-nitrobenzene, its application will become more common.
