0.15 mmol) and LiA1H4 (6 mg) in anhydrous ether (10 mL) was stirred at room temperature for 30 min under anhydrous conditions. The reaction mixture was decomposed by addition of dilute acetic acid, and the ether phase was washed with water, dried, and evaporated to yield an oil. Crystallization from EtOAc gave (+)-la (53 mg, 99%) as a white solid:[. I2, D+ 10.6 O (0.625 g/100 mL, THF); the NMR spectrum of (+)-la was identical with that of the ...
