Question
Chapter 8, Problem 4LGP
Interpretation Introduction
Interpretation:
The structure of possible biosynthetic precursor and the detailed mechanism through which it is formed, is to be drawn.
Concept introduction:
Retrosynthesis: It is the process by which the reaction used to form the target product is deduced, by determining the immediate reactant used to produce it and then repeating the step to determine other precursors.

A chemist synthesized compound X as a racemic mixture. When the ketone group in X was
enzymatically reduced to the corresponding alcohol, a 100% yield was obtained of the product
shown below. Choose the statement that best describes this result.
ОН
enzyme
C;H1
`OCH,CH;
pH 4.0
C3H1
`OCH,CH3
ОН
ÕH
X (racemic)
(100% yield)
One enantiomer of compound X reacts quickly with the enzyme. The other enantiomer of compound X is
unreactive, but rapidly equilibrates with the reactive enantiomer under the reaction conditions.
Since compound X was racemic, it makes sense that only a single product was obtained.
O The product is a meso compound, so either enantiomer of compound X gives the same product.
One enantiomer of compound X reacts quickly with the enzyme, while the other enantiomer of compound X
remains unchanged.
A graduate student was studying enzymatic reductions of cyclohexanones when she encountered some interesting chemistry. When she used an enzyme and NADPH to reduce the following ketone, she was surprised to find that the product was optically active. She carefully repurified the product so that no enzyme, NADPH, or other contaminants were present. Still, the product was optically active. Does the product have any asymmetric carbon atoms or other stereocenters?
The ketone 2-heptanone has been identified as contributing to the odor of a number of dairy products, including condensed milk and cheddar cheese. Describe the synthesis of 2-heptanone from acetylene and any necessary organic and inorganic reagents.

- Cr(VI) compounds are common reagents for the oxidation of alcohols. Primary alcohols are oxidized to carboxylic acids and secondary alcohols are oxidized to ketones.

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.
