3-iodo-2-methoxybenzaldehyde

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 3-iodo-2-methoxy-benzaldehyde (3.68 g, 14 mmol) in tert-butanol (70 mL) was added 2,3-dimethyl-but-2-ene (7 mL) followed by a solution comprising disodium hydrogen phosphate monohydrate (7.56 g 56 mmol) and sodium chlorite (7.56 g, approx. 66 mmol, technical grade) in water (70 mL). The resulting mixture was stirred for 20 minutes then diluted with ethyl acetate, washed with brine, dried over magnesium sulfate and concentrated. The residual solid was recrystallized from cyclohexane to give the title compound as a white solid. washed with brine dried over magnesium sulfate concentrated The residual solid was recrystallized from cyclohexane

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 3-iodo-2-hydroxy-benzaldehyde (4.0 g, 16.06 mmol) in DMA (32 mL) was added cesium carbonate (5.85 g, 18 mmol) followed by methyl iodide (1.12 mL, 18 mmol). The resulting mixture was stirred for 4.75 hours then diluted with ether, washed with water, dried over magnesium sulfate and concentrated. The residue was purified by silica chromatography (50 g silica; eluted with 0-20% ethyl acetate in hexanes) to give the title compound as an oil. washed with water dried over magnesium sulfate concentrated The residue was purified by silica chromatography (50 g silica; eluted with 0-20% ethyl acetate in hexanes)
