(2S)-2-amino-2-cyclopentylethanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a stirred solution of (S)-2-amino-2-cyclopentylacetic acid (1.00 g, 6.98 mmol) in THF (20 mL) was added dropwise a solution of LiAlH4 in THF (1.0 M, 10.5 mL, 10.5 mmol) at 0° C. under N2. The reaction was allowed to warm to ambient temperature and heated at reflux overnight. After cooling, the reaction mixture was cooled to 0° C. and carefully quenched by dropwise addition of water (0.4 mL) followed by 15% NaOH solution (0.4 mL) and water (1.2 mL). The mixture was stirred at ambient temperature for 15 minutes and filtered through Celite. The filtrate was concentrated to give crude (S)-2-amino-2-cyclopentylethanol, which was used in the next step without further purification. heated at reflux overnight After cooling the reaction mixture was cooled to 0° C. carefully quenched by dropwise addition of water (0.4 mL) filtered through Celite The filtrate was concentrated
