130-03-0, Benzo[b]thiophen-3(2H)-one is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a 5 mL flame-dried microwave flask was added benzo[b]thiophen-3(2H)-one (0.24 mmol, 0.12 equiv) and 5-aryl-2-formylpyrrole (0.2 mmol, 0.1 equiv). The flask was capped with analuminume-PTFE crimp cap, sealed, and evacuated and backfilled with nitrogen three times. To the flask was then added anhydrous toluene (2 mL, 0.1M in aldehyde) and piperidine (10 mL, 0.1 mmol,0.5 equiv). The flask was transferred to a pre-warmed oil bath set to 111 C and stirred for 2 h. After 2 h the flask was removed from theoil bath and cooled to room temperature and then to 0 C in a water-ice bath. To the flask was added hexanes (5 mL) and the flask was allowed to sit for an addition 10-30 min. The mixture was the filtered, and the precipitate was then triturated with hexanes to until the filtrate ran clear to provide the pure product as a red, blue,or purple solid depending on the substrate., 130-03-0

130-03-0 Benzo[b]thiophen-3(2H)-one 10986413, abenzothiophene compound, is more and more widely used in various.

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.
