A Br?nsted acid-promoted trifluoromethylselenolation of benzofurans was disclosed by using Se-(trifluoromethyl) 4-methylbenzenesulfonoselenoate as a stable and easily prepared electrophilic trifluoromethylselenolating reagent. A wide range of SeCF3-substituted benzofuran derivatives were obtained in moderate to good yields with excellent regioselectivity. The tandem cyclization/trifluoromethylselenolation procedure of 1-methoxy-2-(arylethynyl)benzenes were also realized by engaging FeCl3 as the catalyst.

Alzheimer's disease (AD) is a type of progressive dementia caused by degeneration of the nervous system. A single target drug usually does not work well. Therefore, multi-target drugs are designed and developed so that one drug can specifically bind to mu

Paragraph 0016-0018, (2018/05/30)
The invention provides a preparation method of a multi-substituted benzofuran derivative. The multi-substituted benzofuran derivative is obtained by taking end alkyne and a halogenated phenol derivative as starting raw materials, copper salt as a catalyst and amino acid as an additive and performing coupling reaction in an organic solvent under the condition of adding alkali, wherein the catalystis CuX, X is iodine or bromine, the molar ratio of the catalyst to the halogenated phenol derivative is (0.001-0.5):1, the molar ratio of the amino acid to the catalyst is (0.1-3):1, the molar ratio of the halogenated phenol derivative to the end alkyne is (1-1.5):1, and the reaction temperature is 30 to 150 DEG C. An expensive palladium catalyst liable to cause environmental pollution is not used. The method is simple in process and high in operability, and has a good industrial application prospect.
