95-15-8,95-15-8, Thianaphthene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: To a cold (-78 C) solution of 50 (16.6 g, 124 mmol) in THF (200 mL) was added n-BuLi (1.60 M in hexane; 78.5 mL, 124 mmol) and the mixture was stirred at -78 C for 1.5 h. To the reaction mixture was added a solution of 64 (29.0 g, 118 mmol) in THF (300 mL) and the mixture was stirred at -78 C for 2 h. To the reaction mixture was added H2O and Et2O and the organic layer was separated, dried over MgSO4, filtered and evaporated in vacuo. The resulting residue was purified by column chromatography on silica gel (EtOAc-hexane) to give alcohol as a pale yellow oil. To a cold (-20 C) solution of this oil (43.3 g, 114 mmol) in CH2Cl2 (800 mL) was added Et3SiH (36.5 mL, 229 mmol) and BF3¡¤OEt2 (15.2 mL, 120 mmol) and the mixture was stirred at -20 C for 30 min. To the reaction mixture was added saturated aqueous sodium bicarbonate solution and the organic layer was separated, dried over MgSO4, filtered and evaporated in vacuo. The resulting residue was purified by column chromatography on silica gel (EtOAc-hexane) to give the title compound (66) (35.6 g, 86%) as a pale yellow oil.
95-15-8 Thianaphthene 7221, abenzothiophene compound, is more and more widely used in various.
