(a) Interpretation: The stereogenic center(s) is to be labeled. Concept introduction: Stereoisomers are the compounds in which molecular formula of a compound remains same but positions of different atoms or groups are changed to form new compounds. The stereogenic centers are also known as sterocenters. The stereocenters are carbon atoms on which the interchanging of two atoms or groups results in the formation of new stereoisomers.

Etoposide, sold as a phosphate derivative with the trade name of Etopophos, is used for the treatment of lung cancer, testicular cancer, and lymphomas. (a) Locate the acetals in etoposide. (b) What products are formed when all of the acetals are hydrolyzed with aqueous acid?

In the 1880's, Acetanilide, sold under the name Antifebrin, was widely used as a pain reliever and fever reducer. However, it had many adverse side effects, including cyanosis as a result of methemoglobinemia. The toxic side effects were the result of a small portion of acetanilide being hydrolyzed to aniline. Acetanilide was discontinued and replaced with phenacetin. Later studies show that both acetanilide and phenacetin are metabolized to acetaminophen. This metabolite, which we know as Tylenol, is responsible for the analgesic and antipyretic properties.
