(b)

Interpretation Introduction

Interpretation:

The possible stereoisomer’s has to be shown if the product is chiral.

Concept introduction:

Chiral:

A molecule is non superimposable on its mirror image is called chiral molecule.  Four different atoms attached to a carbon atom is called chiral molecule.

Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.

Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.

Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.

Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.

Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer.

Achiral:

A molecule is superimposable on its mirror image is called achiral molecule.

    Diazepam, better known as Valium, is a central nervous system (CNS) sedative/ hypnotic. As a sedative, it diminishes activity and excitement and thereby has a calming effect. Back in 1976, based on the number of new and refilled prescriptions processed, diazepam was the most prescribed drug in the United States. Following is a retrosynthetic analysis for a synthesis of diazepam. Note that the formation of compound B involves a Friedel-Crafts acylation. In this reaction, it is necessary to protect the 2° amine by prior treatment with acetic anhydride. The acetyl-protecting group is then removed by treatment with aqueous NaOH followed by careful acidification with HCl. Q. Is diazepam chiral? If so, how many of the possible stereoisomers are formed in this synthesis?
