Add time:07/23/2019 Source:sciencedirect.com
1-(2-Furyl)ethanol 1 was resolved by irreversible transesterification with vinyl acetate using Lipozyme IM or Porcine Pancreas Lipase (PPL) in an organic solvent. (S)-alcohol (99% e.e.) was obtained in 80–85% yield using Lipozyme IM in carbon tetrachloride while (R)-1-(2-furyl)ethyl acetate (96% e.e.) in 75–80% yield resulted from transesterification using Lipozyme IM in hexane or PPL in tetrahydrofuran.
