YieldReaction ConditionsOperation in experiment
93% With selenium(IV) oxide; In 1,4-dioxane; for 3h;Reflux; The 2-methyl-8-methoxy quinoline (10) (3.50g, 20 . 2mmol) by adding 50 ml of dioxane, stirring to dissolve, then adding selenium dioxide (2.20g, 19 . 9mmol), heating reflow 3h. Cooling, filtering, adding activated carbon to the filtrate (1.0g), micro boils 15 min. Is filtered, concentrated under reduced pressure, to obtain yellow solid 3.52g, yield 93%.
93% With selenium(IV) oxide; In 1,4-dioxane; for 4h;Reflux; 2-Methyl-8-methoxyquinoline (2) (3.50 g, 20.2 mmol) was addedDissolved in 80 mL of dioxane, followed by addition of selenium dioxide (2.20 g, 19.9 mmol) and heating under reflux for 4 h. Cooling, filtering, to the filtrate by adding activated carbon (4.0g), micro-boiling 10min. Filtered hot and concentrated under reduced pressure to give 3.52 g of a yellow solid in 93% yield, m.p. 103-104 C (103C).
81% With selenium(IV) oxide; In 1,4-dioxane; at 110℃; for 2h; 8-Methoxy-2-methylquinoline (24) (28.9 mmol) was reacted withSeO2 (52.0 mmol, 1.8 eq) in anhydrous 1,4-dioxane (500 mL) at 110 Cfor 2 h to give 8-methoxyquinoline-2-carboxaldehyde (25). After completionof the reaction; the inorganic compounds were filtered off andpoured into cold water and partitioned with chloroform. The chloroformlayer was concentrated and the crude product obtained was purifiedby column chromatography over silica gel (60-120) usingchloroform as eluent. 8-Methoxyquinoline-2-carbaldehyde (25): yellow solid, yield 81%,m.p. 102-104 C; 1H NMR (CDCl3, 400 MHz): δ 10.32 (s, 1H), 8.29 (d,1H, J=8.4 Hz), 8.08 (d, 1H, J=8.4 Hz), 7.63 (t, 1H, J=8.0 Hz), 7.48(d, 1H, J=8.2 Hz), 7.16 (d, 1H, J=7.8 Hz), 4.17 (s, 3H); 13C NMR(CDCl3, 100 MHz): δ 193.7, 156.1, 151.5, 139.9, 137.3, 131.4, 129.8,119.6, 118.0, 108.6, 56.4; ESI-MS found m/z 187.98 [M+H]+.
With selenium(IV) oxide; In 1,4-dioxane; at 60 - 120℃; for 2.5h; General procedure: o-Anisidine (29) (81.2 mmol) dissolved in 6 M HCl (190The resultant mixture was stirred for 5 min at a temperatureof 100C. Further, crotonaldehyde (30) (162.4 mmol, 2.0equiv.) was added to the reaction mixture dropwise followedby heating at 120C for 3 h. The aqueous layer was extractedwith chloroform after cooling and neutralization by aqueousNaOH solution. The organic layer was dried and purified bycolumn chromatography (silica gel 60-120 , chloroform aseluent) to get 8-methoxy-2-methylquinoline (31)26,27. It wasoxidized using SeO2 in 1,4-dioxane using the above-mentionedprocedure to obtain 8-methoxyquinoline-2-carbaldehyde(32).
