Application of 171290-52-1, These common heterocyclic compound, 171290-52-1, name is 3,5-Dimethoxyphenylacetylene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: To a solution of the azide intermediate (0.1 mmol) in 0.2 mL of DMFin a microwave tube, CuSO4 (0.05 mmol) diluted in 50.0 muL of water,sodium ascorbate (0.025 mmol) and the alkyne (0.2 mmol) were added.The tube was sealed and the solution was irradiated (70 C, 150 W) for10 min and, then, TLC analysis showed the complete consumption ofthe starting material. The reaction was diluted with 15 mL of brine,extracted with ethyl acetate (3×10 mL), dried by anhydrous Na2SO4and concentrated under reduced pressure. The resulting crude productwas purified by column chromatography on silica gel [hexane: ethylacetate, 60:40% (v/v)] yielding the expected product.
Statistics shows that 3,5-Dimethoxyphenylacetylene is playing an increasingly important role. we look forward to future research findings about 171290-52-1.
