Question
Chapter 19, Problem 19.55P
Interpretation Introduction

Interpretation:

A synthesis of nifedipine from 2-nitrobenzaldehyde, methyl acetoacetate and ammonia has to be given.

Concept introduction:

Aldol condensation:

Aldol reaction is an addition reaction of aldehydes and ketones. Aldol reaction is a reversible reaction and occurs in the presence of a strong base like sodium hydroxide. One molecule (aldehyde or ketone) acts a nucleophile and attacks the electrophilic carbon center of the other molecule to give the addition product. The product is named β-hydroxy aldehyde if two aldehydes combine and β-hydroxy ketone if two ketones combine.

Michael reaction:

The reaction occurs with a variety of α,β-unsaturated carbonyl compounds such as aldehydes, esters, nitriles, nitro compounds and amides.

The donor compound of this reaction includes β-diketones, β-keto nitriles, β-keto esters.

Explain how benzaldehyde and dimedone reacts with each other, and then with the aminotriazole to form compound 1a in the presence of an acid catalyst. Provide a detailed reaction mechanism. During the development of the optimized procedure for the experiment, it was found out that compound 1b can also be produced from the same set of starting materials. Propose a detailed reaction mechanism for the formation of 1b. Explain your answer.  What factor/s may drive the formation of 1b over 1a?
Several sulfonylureas, a class of compounds containing RSO2NHCONHR, are useful drugs as orally active replacements for injected insulin in patients with adult-onset diabetes. These drugs decrease blood glucose concentrations by stimulating b cells of the pancreas to release insulin and by increasing the sensitivity of insulin receptors in peripheral tissues to insulin stimulation. Tolbutamide is synthesized by the reaction of the sodium salt of p-toluenesulfonamide and ethyl N-butylcarbamate . Propose a mechanism for this step.
Which of the following sets of reagents would not be an acceptable method for the preparation of ethylacetate? acetic acid, ethanol, and an acid catalyst Acetic anhydride and ethanol Sodium acetate and ethanol Sodium acetate and ethyliodide
