一般描述
(1S,2R)-(+)-Norephedrine is an enantiomer of ephedrine mainly used as a chiral auxiliary for asymmetric synthesis.
应用
(1S,2R)-(+)-Norephedrine may be used in the preparation of dendritic ligands, which on combining with Ru(II) complexes form efficient asymmetric transfer hydrogenation catalysts. It may also be used in the preparation of N-((1S,2R)-1-hydroxy-1-phenylpropan-2-yl)furan-2-carboxamide. This chiral amide can efficiently catalyze the enantioselective ethylation of aromatic and heteroaromatic aldehydes to secondary alcohols in the absence of titanium tetraisopropoxide as promotor.

Growing evidence suggests that peripheral factors to the brain driving neuro-inflammation could affect Alzheimer's Disease (AD) and Parkinson's Disease (PD) severity. Herpes simplex virus type 1 (HSV1) infection has been associated with AD while other related viruses, including cytomegalovirus (CMV)
