Chapter 23: Q7. (page 924)

Question: Draw the product formed when each starting material is treated with LDA in THF solution at –780C.

Short Answer

Expert verified

Answer

The products formed when each starting material is treated with LDA are shown below.

Step by step solution

01

Definition of LDA

LDA is a non-nucleophilic strong base that abstracts protons from the least hindered C-H group.

02

Function of LDA

Due to its bulky nature due to the attached isopropyl groups with the nitrogen atom, it always acts as a base. It withdraws protons from the least hindered site.

The products of the given reaction are:

Reaction of a

Reaction of b

Reaction of c

Reaction of d

Question: Keeping in mind the mechanism for the dissolving metal reduction of alkynes to trans alkenes in Chapter 12, write a stepwise mechanism for the following reaction, which involves the conversion of an α,β-unsaturated carbonyl compound to a carbonyl compound with a new alkyl group on the α carbon.

Question: Devise a synthesis of valproic acid [(CH3CH2CH2)2 CHC02H], a medicine used to treat epileptic seizures, using the malonic ester synthesis.

Question: When phenylacetaldehyde (C6H5CH2CHO) is dissolved in with added DCl, the hydrogen atomsαto the carbonyl are gradually replaced by deuterium atoms. Write a mechanism for this process that involves enols as intermediates.

Question: Vitamin C is a stable enediol. Draw the structure of the two keto tautomers in equilibrium with the enediol and explain why the enediol is more stable than the other tautomer.

Question: Although ibuprofen is sold as a racemic mixture, only the S enantiomer acts as an analgesic. In the body, however, some of the R enantiomer is converted to the S isomer by tautomerization to an enol and then protonation to regenerate the carbonyl compound. Write a stepwise mechanism for this isomerization.
