With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.42923-77-3,6-Methoxy-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.
General procedure: To a dried sealed vessel was added 1,2,3,4-tetrahydroisoquinoline (5 mL, 40 mmol), anhydrous K2CO3 (8.34 g,60 mmol), CuI (0.8 g, 4 mmol), L-Proline (0.92 g, 8 mmol), ethyl 6-bromopicolinate (4.32 g, 20 mmol), and DMSO (25 mL). Then themixture was stirred at 80 C for 16 h under N2 environment. Aftercooling to room temperature, water (100 mL) was added andextracted with EtOAc. Then, the combined organic layer was driedover MgSO4, filtered, and concentrated. The residue was purified bysilica gel flash chromatography (hexane/EtOAc = 5/1) to providecompound 14 as a white oil (3.94 g, 70%).
The synthetic route of 42923-77-3 has been constantly updated, and we look forward to future research findings.
