(a)
Interpretation:
The synthesis of fexofenadin has to be shown.
Concept introduction:
The Grignard reaction:
Alkyl, vinyl, or aryl-magnesium halides (
(b)
Interpretation:
The possible stereoisomer’s has to be shown if the product is chiral.
Concept introduction:
Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.
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.
Achiral:
A molecule is superimposable on its mirror image is called achiral molecule.

- A simple, reversible competitive antagonist is expected to acutely: Reduce both the potency and efficacy of an agonist O Increase the potency of an agonist O Reduce the potency of an agonist Reduce the efficacy of an agonistarrow_forwardWhy is methyl salicylate so easily absorbed through the skin?arrow_forwardN-Methylpyrrolidine has a boiling point of 81 °C, and piperidine has a boiling point of 106 °C. Tetrahydropyran has a boiling point of 88 °C, and cyclopentanone has a boiling point of 141 °C. These two isomershave a boiling point difference of 53 °C. Explain why the two oxygen-containing isomers have a much larger boilingpoint difference than the two amine isomersarrow_forward

- Explain the effect of the atypical antipsychotic cariprazine on CNS receptors in relation to potential clinical benefits on schizophrenic symptoms and unwanted effects.arrow_forwardParoxetine (Paxil) is an antidepressant that is a member of a family of drugs known as Selective Serotonin Reuptake Inhibitors (SSRIS). This family of drugs also includes fluoxetine (Prozac) and sertraline (Zoloft). SSRIS work by inhibiting the reuptake of the neurotransmitter serotonin in the synapses of the central nervous system follow- ing release of serotonin during excitation of individual nerve cells. Between firings, the serotonin is taken back up by a nerve cell in preparation for firing again. Inhibition of reuptake has the effect of increasing the time serotonin molecules remain in the syn- apses following excitation, leading to a therapeutic effect. In one synthesis of parox- etine, the following reagents are used. Draw the structures of synthetic intermediates A and B.
