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