| Abstract: | Racemic 2-nitro-1-phenylethanol was resolved by via enantioselective transesterification catalyzed by Burkholderia cepacia lipase. The reaction afforded excellent E values (E > 200) and enantioselectivity (up to >99% enantiomeric excesses ee]) of both remaining substrates and acetylated product.
Moreover, the lipase displayed high enantioselectivity in the resolution of additional 2-nitroalcohols (E up to >200). This method provides an efficient alternative for obtaining enantiopure 2-nitroalcohols. |
