With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.90806-58-9,5-Methoxyisoquinoline,as a common compound, the synthetic route is as follows.,90806-58-9
General procedure: The mixture of isoquinoline 1 (1.3 mmol), terminal alkyne 2 (1.0 mmol), methylperfluoroalk-2-ynoates 3 (1.5 mmol), and CuBr (0.1 mmol) was stirred in toluene (5 mL) under N2. After stirring at room temperature for 24 h, CuBr2 (0.2 mmol), pyridine (1.0 equiv) were added. The mixture was stirred at 100 C under air for an additional 16 h. Then, the reaction was quenched with water and extracted with ethyl acetate (3¡Á5 mL). The combined extracts were washed with brine, dried over anhydrous Na2SO4, and filtered. The filtrate was concentrated. The crude product was purified by flash chromatography on a silica gel (eluent: petroleum ether /ethylacetate) to give pure 5a-5q.
As the paragraph descriping shows that 90806-58-9 is playing an increasingly important role.
