실험 절차

The resulting catalyst residue was dissolved in (2R)-6-fluoro-2-[(2S)-oxiran-2-yl]-3,4-dihydro-2H-chromene (0.97 g), (2R)-6-fluoro-2-[(2R)-oxiran-2-yl]-3,4-dihydro-2H-chromene (0.97 g) [(R,R)-,(R,S)-epoxide diastereoisomeric mixture)] and MTBE (2.36 ml) and the mixture obtained was treated with H2O (0.099 g).
