実験手順

A racemic mixture of benzyl (tetrahydrofuran-3-yl)methylcarbamate was dissolved in tetrahydrofuran and separated by liquid chromatography with a Chiralpak IC 2.5 cm ID×25 cm, 20 micron column, eleuting with hexane/tetrahydrofuran/isopropanol (85/10/5), to provide (R)-benzyl (tetrahydrofuran-3-yl)methylcarbamate and (S)-benzyl (tetrahydrofuran-3-yl)methylcarbamate.
