The preparation of diazepam compound has to be proposed. Concept Introduction: Retrosynthetic analysis: In an organic synthesis , the transformation of target molecule into simpler precursor molecules regardless of any reactivity or interaction with reagents. A retrosynthetic analysis is involving the breaking of a bond to form two or more synthons.

Question

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.

Question

Chapter 22, Problem 22.52P

(a)

Interpretation Introduction

Interpretation:

The preparation of diazepam compound has to be proposed.

Concept Introduction:

Retrosynthetic analysis:

In an organic synthesis, the transformation of target molecule into simpler precursor molecules regardless of any reactivity or interaction with reagents. A retrosynthetic analysis is involving the breaking of a bond to form two or more synthons.

(b)

Interpretation Introduction

Interpretation:

The chirality of diazepam, and the possible of number of isomers in the given synthesis has to be given.

Concept Introduction:

Stereoisomers and chiral:

Isomers differing only in their spatial arrangement of atoms are called as stereoisomers.

The geometric property of a molecule that cannot be superimposed on its mirror image is known as chirality. Chiral carbon is the one which is attached with four different groups or atoms.
