2,6-dimethyloxan-4-ol

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

実験手順: 2,6-Dimethyl-4H-pyran-4one (5.0 g) in ethanol (40 ml) was hydrogenated under 10% Pd—C (0.5 g) at 10 bar of hydrogen for 2 days. The solution was then evaporated to an oil which was purified by silica-gel MPLC [using a 1:1 mixture of ethyl acetate and hexane as eluant] to give the title product (3.71 g, 74%). The solution was then evaporated to an oil which was purified by silica-gel MPLC [ a 1:1 mixture of ethyl acetate and hexane as eluant]
