Naproxen, a nonsteroidal anti-inflammatory drug that is the active ingredient in Aleve (p. 115), has a specific rotation of +66. One commercial preparation result in a mixture with a 97% enantiomeric excess.
a. Does naproxen have the R or the S configuration?
b. What percent of each enantiomer is obtained from the commercial preparation?
A student decided that the configuration of the asymmetric centers in a sugar such as d-glucose could be determined rapidly by simply assigning the Rconfiguration to an asymmetric center with an OH group on the right and the Sconfiguration to an asymmetric center with an OH group on the left. Is
he correct? (We will see in Chapter 20 that the “d” in d-glucose means that the OH group on the bottommost asymmetric center is on the right.)
