2-methyl-6-propan-2-ylbenzaldehyde

反応条件: temp:0.00; pressure:0.00; stir:

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

実験手順: To a solution of 2-isopropyl-6-methylbenzaldehyd (1.75 g, 10.8 mmol) in methanol (15 ml) was added sodium borohydride (0.35 g, 9.5 mmol) and the mixture was stirred 1 h. at room temperature. The solvent was evaporated under reduced pressure and to the residue was added hexane and water. The organic layer was separated and evaporated under reduced pressure to give 1.73 g (98%) of the title compound as an oil. The solvent was evaporated under reduced pressure and to the residue was added hexane and water The organic layer was separated evaporated under reduced pressure

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

実験手順: To a solution of 1-bromo-2-isopropyl-6-methylbenzene (6.9 g, 32.4 mmol) in diethyl ether (50 ml) was added magnesium turnings (0.9 g, 37 mmol) and the mixture was refluxed in nitrogen atmosphere until the reaction was started and was then stirred overnight at room temperature. Dimethylformamide (4 ml) was added dropwise during 10 min. and the mixture was stirred for 30 min. Saturated ammmoniumchloride solution (30 ml) was added and the mixture was stirred for 1 h. The organic layer was separated, filtrated and evaporated under reduced pressure. Purification by column chromatography on silica gel using hexane:methylene chloride (3:2) as eluent gave 1.75 g (33%) of the title compound . the mixture was refluxed in nitrogen atmosphere until the reaction the mixture was stirred for 30 min the mixture was stirred for 1 h The organic layer was separated filtrated evaporated under reduced pressure Purification by column chromatography on silica gel
