(4-methoxycyclohexyl)methanol

反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a mixture of (4-methoxy-cyclohexyl)-methanol (1.25 g, 8.7 mmol) and trifluoromethanesulfonic acid 3-bromo-propyl ester (2.58 g, 9.55 mmol) in nitromethane (15 ml) was added 2,6-di-tert-butylpyridine (1.83 ml, 9.55 mmol). The reaction mixture was heated at 80° C. for 18 hours. The mixture was concentrated in vacuo and the residue purified by flash column chromatography on silica eluting with 20% ethyl acetate in hexane to give the title compound as a yellow oil (1.4 g, 61%). The mixture was concentrated in vacuo the residue purified by flash column chromatography on silica eluting with 20% ethyl acetate in hexane

実験手順: 13.7 ml (27.5 mmol) of lithium aluminium hydride solution (2M in THF) was diluted with 82 ml of methyl tert-butyl ether, and a solution of 4.30 g (25.0 mmol) of methyl 4-methoxycyclohexanecarboxylate (cis/trans isomer mixture) in 82 ml of methyl tert-butyl ether was then added dropwise. The reaction solution was stirred at 40° C. for another 6 h and the reaction was then terminated by addition of 10 ml of water and 10 ml of aqueous 10% strength potassium hydroxide solution. The organic phase was decanted, dried over sodium sulphate and filtered, and the solvent was removed under reduced pressure. Yield: 3.24 g (90% of theory) the reaction was then terminated by addition of 10 ml of water and 10 ml of aqueous 10% strength potassium hydroxide solution The organic phase was decanted dried over sodium sulphate filtered the solvent was removed under reduced pressure
