一般說明

(1R,2S)-(-)-Ephedrine, a chiral β-amino alcohol, is commonly used as a chiral auxiliary in asymmetric synthesis. It undergoes reduction to form (+)-methamphetamine.

應用

通用手性合成子，用于催化以及制备光学纯亚砜和噁唑烷。
(1R,2S)-(-)-Ephedrine can be used in the preparation of optically active phosphine-phosphonite ligands and chirally-substituted cyclopentadienyl (Cp) ligands. It reacts with phosphorus trichloride to form (2R,4S,5R)-2-chloro-3,4-dimethyl-5-phenyl-1,3,2-oxazaphospholidine. It can also act as a chiral resolving agent for (±)-mandelic acid.

Brown adipose tissue (BAT) activation increases energy consumption and may help in the treatment of obesity. Cold exposure is the main physiological stimulus for BAT thermogenesis and the sympathetic nervous system, which innervates BAT, is essential in this process. However
