(a)
Interpretation:
The synthesis of propranolol has to be shown from 1-naphthol.
(b)
Interpretation:
The chirality of Propranolol is to be identified and the possible stereoisomers has to be identified in the given synthesis.
Concept introduction:
Chiral:
A molecule is non superimposable on its mirror image is called chiral molecule.
Four different atoms attached to a carbon atom is called chiral molecule.
Isomer:
A molecule having the same molecular formula but with different chemical structure is called isomer.
Stereoisomers:
Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
Enantiomers:
A compound which is non-superimposable mirror image is called enantiomers.
Diastereomers:
A compound which is non-superimposable and non-mirror image is called diastereomers.
Racemic mixture:
A racemic mixture is simply a mixture containing an equal amount of each enantiomer.

- Show how acid derivatives hydrolyze to carboxylic acids under either acidic or basicconditions. Explain why some acid derivatives (amides, for example) require muchstronger conditions for hydrolysis than other derivatives.arrow_forwardThe substance provided can be prepared by a nucleophilic addition reaction between an aldehydeor ketone and nucleophile. Identify the reactants from which it was prepared. If the substance is an acetal, identify the carbonyl compound and the alcohol; if it is an imine or enamine, identify the carbonyl compound and the amine.arrow_forwardTreatment of pentanedioic (glutaric) anhydride with ammonia at elevated temperature leads to a compound of molecular formula C5H7NO2. What is the structure of this product? [Hint: You need to think about the reactivity not only of acid anhydrides but also of amides and carboxylic acids]arrow_forward
- Nifedipine (Procardia and Adalat) belongs to a class of drugs called calcium channel blockers and is effective in the treatment of various types of angina, including that in- duced by exercise. Show how nifedipine can be synthesized from 2-nitrobenzaldehyde, methyl acetoacetate, and ammonia. (Hint: Review the chemistry of your answers to Problems 19.43 and 19.54 and then combine that chemistry to solve this problem.) NO COOME MEOOC, acid + 2 `NO2 OMe +NH3 СНО H Nifedipinearrow_forwardDuring the decarboxylation of acetoacetate, what is the nucleophile and what is the electrophile? Is the formation of a schiff base simply a preparation step or is the formation of a schiff base formed also by nucleophile/electrophile interaction?arrow_forwardThe hydrolysis of the ester shown here is catalyzed by morpholine. Explain how morpholine catalyzes the reaction. (Hint: The pKa of the conjugateacid of morpholine is 9.3, so morpholine is too weak a base to function as a base catalyst.)arrow_forward
- Why is methyl salicylate so easily absorbed through the skin?arrow_forwardEarly organic chemists used the Hofmann elimination reaction as the last step of a process known as a Hofmann degradation—a method used to identify amines. In a Hofmann degradation, an amine is methylated with excess methyl iodide in a basic solution, treated with silver oxide to convert the quaternary ammonium iodide to a quaternary ammonium hydroxide, and then heated to allow it to undergo a Hofmann elimination. Once the alkene product is identified, working backward gives the structure of the amine. Identify the amine in each of the following cases: a. 4-Methyl-2-pentene is obtained from the Hofmann degradation of a primary amine. b. 3-Methyl-1-butene is obtained from the Hofmann degradation of a primary amine. c. 2-Methyl-1-3-butadiene is obtained from two successive Hofmann degradations of a secondary amine.arrow_forwardKnow classification/mechanism of inhibition for: phenolics, halogens, oxidizers, heavy metals, surfactants (quaternary ammonium halide, soaps, detergents), alcohols, alkylating agents.

- Provide the systematic name for each of the following isomeric amides with the chemical formula C,HNO. (Be sure to indicate double bond stereochemistry using (E)/(Z) notation. Indicate stereochemistry in rings with the terms cis or trans. It is not necessary to use italics in writing compound names.)
