2058-74-4,Some common heterocyclic compound, 2058-74-4, name is 1-Methylisatin, molecular formula is C9H7NO2, 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.
A solution of N-methylisatin (322 mg, 2.0 mmol), phenylacethylene (306 mg, 3.0 mmol), CuI (76 mg, 0.4 mmol), and Cs2CO3 (978 mg, 3.0 mmol) in CH3CN (4.0 mL) was stirred at room temperature for 18 h. After aqueous extractive workup and column chromatographic purification process (CH2Cl2/EtOAc, 15:1) 1a was obtained as a pale yellow soild, 347 mg (66%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Methylisatin, its application will become more common.
