With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.130-03-0,Benzo[b]thiophen-3(2H)-one,as a common compound, the synthetic route is as follows.
General procedure: To a stirred mixture of ketone 1a or 1b (3 mmol) and diarylpropargylic alcohols 2a-e (3 ml) in acetonitrile (3 ml) the corresponding catalyst (Table 1) was added and the reaction mixture was refluxed under argon for 1 h. After cooling, the solvent was distilled off in vacuo. The residue was purified by recrystallization from the corresponding solvent or by chromatography on silica gel using the light petroleum/ethyl acetate (8:1) system as an eluent., 130-03-0
As the paragraph descriping shows that 130-03-0 is playing an increasingly important role.
