Aldehydes and Ketones

Aldehydes and ketones are organic compounds that have a carbonyl group, C = O, as their functional group. They both differ in the placement of this carbonyl group in their structures.

Textbook Question

Chapter 5, Problem 5.39SP

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.

Chapter 5, Problem 5.39SP, A graduate student was studying enzymatic reductions of cyclohexanones when she encountered some

a. (a) Does the product have any asymmetric carbon atoms or other stereocenters?
b. (b) Is the product capable of showing optical activity? If it is, explain how.
c. (c) If this reaction could be accomplished using H₂ and a nickel catalyst, would the product be optically active? Explain.

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone

Friedel–Crafts alkylation of benzene with (R)-2-chlorobutane and AlCl3 affords sec-butylbenzene.a. How many stereogenic centers are present in the product?b. Would you expect the product to exhibit optical activity? Explain, with reference to the mechanism.

A compound A, C7H12, was found to be optically active. On catalytic reduction over platinum catalyst, 2 equivalents of hydrogen were absorbed, yielding compound B, C7H16. On ozonolysis of A, two fragments were obtained. One fragment was identified as acetic acid. The other fragment, compound C, was an optically active carboxylic acid, C5H10O2. Write the reactions and draw structures for A, B and C.

A difficult problem in the synthesis of PGF2α is the introduction of the OH group at C15 in the desired configuration. a. Label this stereogenic center as R or S. b. A well known synthesis of PGF2α involves reaction of A with Zn(BH4)2, a metal hydride reagent similar in reactivity to NaBH4, to form two isomeric products, B and C. Draw their structures and indicate their stereochemical relationship. c. Suggest a reagent to convert A to the single stereoisomer X.
