Versuchsvorschrift

To a cooled solution (0° C.) of (E)-ethyl dec-4-enoate (20 g, 101 mmol) in anhydrous diethyl ether (350 mL) was added lithium aluminum hydride (8.9 g, 212 mmol) under nitrogen. The solution was stirred for 1 hour at room then cooled to 0° C. and quenched slowly with 5M NaOH (30 mL) and diluted with ethyl ether (100 mL). The solution was stirred for 30 min and dried on magnesium sulfate, filtered and concentrated vacuo to dryness to afford (E)-dec-4-en-1-ol 84 as oil (16.1 g, quantitative).
