Describe how mescaline can be synthesized from benzene.
How imines and enamines are converted back to carbonyl compounds by hydrolysis with mild acid ?
Prostaglandins are a class of cicosanoids, fatty acid derivatives with a variety of extremely potent actions on vertebrate tissues.
They are responsible for producing fever and inflammation and its associated pain. Prostaglandins are derived from the 20-
carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin endoperoxide synthase. This enzyme, a
cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the immediate precursor of many different prostaglandins.

- Paroxetine (Paxil) is an antidepressant that is a member of a family of drugs known as Selective Serotonin Reuptake Inhibitors (SSRIS). This family of drugs also includes fluoxetine (Prozac) and sertraline (Zoloft). SSRIS work by inhibiting the reuptake of the neurotransmitter serotonin in the synapses of the central nervous system follow- ing release of serotonin during excitation of individual nerve cells. Between firings, the serotonin is taken back up by a nerve cell in preparation for firing again. Inhibition of reuptake has the effect of increasing the time serotonin molecules remain in the syn- apses following excitation, leading to a therapeutic effect. In one synthesis of parox- etine, the following reagents are used. Draw the structures of synthetic intermediates A and B.

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.
