With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3541-37-5,Benzo[b]thiophene-2-carboxaldehyde,as a common compound, the synthetic route is as follows.
General procedure: A mixture of amine 1 (46.4mg, 0.24mmol), 2-(trimethylsilyl)phenyl triflate (89.5mg, 0.30mmol), CsF (91.1mg, 0.60mmol), and acetonitrile (0.80mL) in a sealed tube was heated at 60C (oil bath) for 10 min, and a solution of aldehyde 2 (0.20mmol) in acetonitrile (0.40mL) was added. The mixture was stirred at 60C for 24h, cooled to room temperature, and purified by silica gel chromatography, eluting with ethyl acetate/petroleum ether (1:10 v/v), to give epoxide 3.
3541-37-5, 3541-37-5 Benzo[b]thiophene-2-carboxaldehyde 736500, abenzothiophene compound, is more and more widely used in various fields.
