As a common heterocyclic compound, it belongs to tetrahydroisoquinoline compound, name is 6-Methoxy-1,2,3,4-tetrahydroisoquinoline, and cas is 42923-77-3, its synthesis route is as follows.,42923-77-3
To a cooled (0 oC) solution of 1,1?-carbonyldiimidazole (350 mg, 2.20 mmol) in anhydrous MeCN (25 mL) was added THIQ 14 (326 mg, 2.00 mmol) and K2CO3 (4.00 mmol). The resulting mixture was stirred at 24 oC for 18 h and then concentrated under reduced pressure to afford a residue which was purified by column chromatography (100% EtOAc) to give imidazole 15 (493 mg, 96%) as a colourless oil, Rf 0.31 (100% EtOAc). This intermediate was immediately used without further purification in the next synthetic step. 1H NMR (300 MHz, CDCl3): deltaH 7.86 (d, J 0.9 Hz, 1H, imidazole-H), 7.20 (d, J 1.4 Hz, 1H, imidazole-H), 7.05 (d, J 1.4 Hz, 1H, imidazole-H), 6.95-6.92 (m, 1H, ArH), 6.71-6.64 (m, 2H, ArH), 4.61 (s, 2H, ArCH2N), 3.78-3.67 (m, 5H, overlapping signals – NCH2 and OMe), 2.90 (t, J 6.0 Hz, 2H, ArCH2CH2). 13C NMR (75 MHz, CDCl3): deltaC 29.1 (ArCH2CH2), 44.7 (CH2CH2N), 48.3 (ArCH2N), 55.6 (OMe), 113.3 (ArCH), 113.9 (ArCH), 118.2 (ArCH), 124.1 (ArC), 127.6 (ArCH), 130.1 (ArCH), 135.3 (ArC), 137.1 (ArCH), 151.4 (C-O), 159.0 (C=O).
With the complex challenges of chemical substances, we look forward to future research findings about 42923-77-3,belong tetrahydroisoquinoline compound
