![For centuries, Chinese herbal medicine has used extracts of Ephedra sinica to treat asthma.
Ephedra as an"herbal supplement" has been implicated in the deaths of several athletes
and has recently been banned as a dietary supplement. Phytochemical investigation of
this plant resulted in isolation of ephedrine, a very potent dilator of the air passages of
the lungs. Ephedrine also has profound effects on the cardiovascular system. The natu-
rally occurring stereoisomer is levorotatory and has the following structure. Assign an
Ror S configuration to each chiral center.
