Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 171290-52-1, name is 3,5-Dimethoxyphenylacetylene, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 171290-52-1
Formula 7 of the azide compound (300 mumol), alkynyl (750 mumol), CuSO4 (9.6 mg, 60 mumol) and Na. An ascorbate (60.0 mg, 300 mumol) 1: was dissolved in 1 t-BuOH / H2O (3 mL). The mixture was stirred at room temperature for 2 hours. After the reaction was completed, the mixture was filtered of and washed using H2O (70 mL) (solid A). The filtrate was extracted with EtOAc (3 ¡Á 70 mL). The combined organic extracts were then dried using anhydrous MgSO4, filtered and concentrated by rotaryevaporation (residue B). It was combined and the solid residue A and B, was purified by column chromatography to give the compound of formula 2 and 3. Following the general method for the general formula 2, 1: 1 t-BuOH / H2O (3 mL) in the compound 7d (85.3 mg, 300 mumol),1-ethynyl -3,5-dimethoxy-benzene (121 mg, 750 mumol), CuSO4 (9.6 mg, 60 mumol) and Na. Using ascorbate (60.0 mg, 300 mumol) was prepared in the desired compound. The reaction mixture was stirred at 40 for 47 hours, was purified by column chromatography (5: 1 hexane / EtOAc ? 20: 1 CH2Cl2 / MeOH) to yield a compound 2d as a brown solid using (98.8mg, 74%) .
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 171290-52-1.
