Versuchsvorschrift
A mixture of (3S,4S)-tetrahydrofuran-3,4-diol (9.35 g, 89.8 mmol), t-butyldimethylchlorosilane (14.9 g, 98.8 mmol), TEA (13.8 mL, 98.8 mmol), and dichloromethane (100 mL) is stirred at room temperature for 4 days. The reaction is concentrated in vacuo and purified on silica gel (330 g, 35-80% EtOAc/hexanes, observed on TLC using KMnO4 staining) to give 3.66 g (19%) of the title compound as a light yellow oil. GC-MS m/z 161 (M-tBu)+.
