Methyl bromoacetate → Oleyl bromoacetate

참여 물질

반응 단계

Technical grade oleyl alcohol (85 wt %; 10 g; 37.2 mmol) was combined with Novozym 435 (200 mg) in an amber bottle. Methyl bromoacetate (6.84 g; 44.7 mmol; 1.2 equiv.) was added, and the mixture was sealed and stirred at room temperature overnight to afford about 50% conversion to oleyl bromoacetate. The mixture was then purged with a subsurface stream of nitrogen 2.5 days to afford 98.5% conversion of oleyl alcohol to oleyl bromoacetate according to GC analysis. The mixture was filtered, and the solid was washed with toluene. The filtrate was concentrated to give the desired product as a viscous colorless oil (13.19 g, 91%). The product was used in the subsequent reactions without further purification.
