The shrub ma huang contains two biologically active stereoisomers - ephedrine and pseudoephedrine - with two stereogenic centers as shown in the given structure. Ephedrine is one component of a once popular combination drug used by bodybuilders to increase energy and alertness, while pseudoephedrine is a nasal decongestant. Draw the structure of naturally occurring (-)-ephedrine, which has the 1R, 2S configuration. Click the "draw structure" button to launch the drawing utility.
