Water → tert-Butyl [(1S,2S)-2-hydroxycyclopentyl]carbamate

Participants

Reaction Steps

tert-Butyl N-[(1S,2S)-2-trimethylsilyloxycyclopentyl]carbamate (15.5 g, 56.7 mmol) and tetrabutylammonium fluoride (85.0 mL, 85.0 mmol) in THF (113 mL) are stirred at room temperature for 1 h. Water (50 mL) is added and the mixture is concentrated in vacuo to remove the THF. The resulting mixture is extracted with EtOAc (3×75 mL). The combined organic portions are washed with brine (2×30 mL), dried over sodium sulfate, filtered, and concentrated to give 14.7 g of crude product as a yellow oil. The material is purified on silica gel (330 g) using 25% EtOAc/hexanes to give the title compound as a white solid (10.25 g, 90%). LC-ES/MS m/z 224 (M+Na).
