Some common heterocyclic compound, 3672-47-7, name is 3-(4-Methoxyphenyl)-3-oxopropanenitrile, molecular formula is C10H9NO2, 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. Application In Synthesis of 3-(4-Methoxyphenyl)-3-oxopropanenitrile
General procedure: Benzoyl acetonitrile (1, 0.5 mmol), cyclic 2-diazo-1,3-dicarbonyl compound (2, 1.25 mmol), [RhCp*Cl2]2 (0.025 mmol), CsOAc (0.25 mmol), Cu(OAc)2*H2O (1.0 mmol) and DCE (2 mL) were sequentially charged into a reaction tube. The tube was then sealed and the mixture was stirred at 80 C. Upon completion, it was cooled to room temperature, quenched with saturated brine (10 mL), and extracted with EtOAc (10 mL * 3). The combined organic phase was dried over anhydrous Na2SO4, and concentrated under reduced pressure. The residue was purified by silica gel chromatography using petroleum ether/ethyl acetate (5:1) as eluent to afford 3.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3672-47-7, its application will become more common.
