A student was trying to determine the identity of an unknown compound. The melting point of the compound was 117-118oC. The student narrowed the possible compound down to the following: Compound Melting Point Range acetanilide 113-115oC fluorene 114-116oC mandelic acid 120-122oC Explain in detail how the student can experimentally determine and confirm the identity of their unknown.
When the (R,R) isomer of the amine shown is treated with an excess of methyl iodide, then silver oxide, then heated, the majorproduct is the Hofmann product.) Some Zaitsev product is also formed. It has the (E) configuration. When the same amine is treated with mCPBA and heated, theZaitsev product has the (Z) configuration. Use stereochemical drawings of the transition states to explain these observations
ripelennamine is a histamine H1 antagonist with low sedative action but frequent gastrointestinal irritation. It is used to treat asthma; hay fever; urticaria; and rhinitis. Based on biotransformations discussed in class, draw the structures of 3 possible metabolites of tripelennamine.
Brucine is a poisonous alkaloid obtained from Strychnos nux vomica, a tree that grows in India, Sri Lanka, and northern Australia. Write out a resolution scheme, which shows how a racemic mixture of phenylalanine can be resolved using brucine.
Please help: Epilepsy is often treated with a combination of drugs such as carbamazepine and phenytoin (polytherapy). CYP3A4 is induced by phenytoin and carbamazepine. Carbamzeipine is cleared by CYP3A4, but phenytoin is not cleared by CYP3A4. What problems might you expect if (a) carbamazepine is removed or (b) phenytoin is removed from this two-drug regimen.
Several compounds have been found to inhibit -lactamase, and drugs based on these compounds can be taken in combination with penicillins and cephalosporins to restore their effectiveness when resistance is known to be a problem. The commonly prescribed formulation called Augmentin is a combination of the -lactamase inhibitor shown below with amoxicillin (shown above). It is used to treat childhood ear infections when resistance is suspected, and many kids know it as the white liquid that tastes like bananas. Which of the statements below are true statements? 1. The stereochemistry of the fusion between the four-and five-membered rings in the inhibitor and amoxicillin are different. 2. The inhibitor possesses enol ether and allylic alcohol functional groups while the antibiotic possesses a phenol and a secondary amide functional group. 3. Neither the inhibitor nor the antibiotic contains strained rings. 4. Both 1 and 2 are true.
The following three derivatives of succinimide are anticonvulsants that have found use in the treatment of epilepsy, particularly petit mal seizures. Q. Show how this same synthetic strategy can be used to prepare ethosuximide and methsuximide.
Which of the amines listed next is resolved into enantiomers? In each case, explain whyinterconversion of the enantiomers does or does not take place.N-methylaziridine
d-Glucuronic acid is found widely in plants and animals. One of its functions is to detoxify poisonous HO-containing compoundsby reacting with them in the liver to form glucuronides. Glucuronides are water soluble and therefore readily excreted. Afteringestion of a poison such as turpentine or phenol, the glucuronides of these compounds are found in the urine. Draw thestructure of the a- and b-glucuronides formed by the reaction of b-d-glucuronic acid and phenol.
Thalidomide is a chiral molecule and it was identified that the R-isomerproduced the sedative properties whereas the S-isomer produced the teratogenic effects.Identify the chiral centre in the thalidomide molecule and, using your knowledge of enolisation, illustrate mechanistically, and explain, why there would be no benefit to a patient taking the chirally pure R-isomer of the drug to avoid the sideeffects of the other enantiomer.
