Concept Introduction:
In the acid-catalyzed ring-opening of an epoxide with water, first proton transfer takes place and then nucleophilic attack takes place via the SN2 mechanism. In the end, proton transfer step takes place that removes the charge formed after the attack of the neutral nucleophile on a more substituted position. Similarly, ring opening of epoxide can also take place in a basic medium. This results in an attack of the nucleophile on a less substituted position.

Grignard reagent is a versatile tool in synthetic organic chemistry. Using bromocyclopentane as a starting material, show how a Grignard reagent, X, is synthesized.
Reaction of X with water produces compound Y while treatment in carbon dioxide followed by hydrolysis forms compound Z. 3-methyl-2butanone reacts with X and hydrolyses to yield compound AA. Draw the structural formulae of compounds Y, Z and AA and write the chemical equations respectively.
3. Isoerythrogenic acid, C18H26O2, is an acetylenic fatty acid that turns a vivid blue on
exposure to UV light. On Catalytic hydrogenation over a palladium catalyst, five molar
equivalents of hydrogen are absorbed, and stearic acid, CH3(CH2)16CO2H, is produced.
Ozonolysis of isoerythrogenic acid yields the following products: formaldehyde, CH2O,
malonic acid, HO2CCH2CO2H, adipic acid, HO2C(CH2)4CO2H, and the aldehyde
carboxylic acid, OHC(CH2)6CO2H. Provide a structure for isoerythrogenic acid.
Treatment of anthranilic acid with nitrous acid gives an intermediate, A, that contains a
diazonium ion and a carboxylate group. When this intermediate is heated in the pres-
ence of furan, a tricyclic compound is formed. Propose a structural formula for com-
pound A and a mechanism for the formation of the tricyclic product.

- 18. Compound A (C7H₁1Br) is treated with magnesium in ether to give B (C7H11MgBr) which reacts violently with D2O to give 1-methylcyclohexene with a deuterium atom on the methyl group (C). Reaction of B with acetone followed by hydrolysis gives D (C10H180). Heating D with concentrated H2SO4 gives E (C10H16), which decolorizes two equivalents of Br2 to give F (C10H16Br4). E undergoes hydrogenation with excess of H₂ and a Pt catalyst to give isobutylcyclohexane.

- Amines are converted into alkenes by a two-step process called Hofmann elimination. SN2 reaction of the amine with an excess of CH3I in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as base. Pentylamine, for example, yields 1-pentene. Propose a structure for the intermediate, and explain why it readily undergoes elimination.arrow_forwardAldehydes and ketones undergo acid-catalyzed reaction with alcohols to yield hemiacetals, compounds that have one alcohol-like oxygen and one ether-like oxygen bonded to the same carbon. Further reaction of a hemiacetal with alcohol then yields an acetal, a compound that has two ether-like oxygens bonded to the same carbon. (a) Show the structures of the hemiacetal and acetal you would obtain by reaction of cyclohexanone with ethanol. (b) Propose a mechanism for the conversion of a hemiacetal into an acetal.arrow_forwardWhen warmed in dilute sulfuric acid, 1-phenyl-1,2-propanediol undergoes dehydration and rearrangement to give 2-phenylpropanal.

(b) Account for the fact that 2-phenylpropanal is formed rather than its constitutional isomer, 1-phenyl-1-propanone.arrow_forward
- Alcohols are important for organic synthesis, especially in situations involving alkenes. The alcohol might be the desired product, or the OH group might be transformed into another functional group via halogenation, oxidation, or perhaps conversion to a sulfonic ester derivative. Formation of an alcohol from an alkene is particularly powerful because conditions can be chosen to produce either the Markovnikov or non-Markovnikov product from an unsymmetrical alkene. Using your reaction roadmap as a guide, show how to convert 4-methyl-1-pentene into 5-methylhexanenitrile. You must use 4-methyl-1-pentene and sodium cyanide as the source of all carbon atoms in the target molecule. Show all reagents needed and all molecules synthesized along the way.arrow_forwardA newer generation of antipsychotics, among them clozapine, are now used to treat the symptoms of schizophrenia. These drugs are more effective than earlier drugs in improving patient response in the areas of social withdrawal, apathy, memory, comprehension, and judgment. They also produce fewer side effects such as seizures and tardive dyskinesia (involuntary body movements). In the following synthesis of clozapine, Step 1 is an Ullmann coupling, a type of nucleophilic aromatic substitution that uses a copper catalyst. (a) Show how you might bring about formation of the amide in Step 2. (b) Propose a reagent for Step 3. (c) Propose a mechanism for Step 4. (d) Is clozapine chiral? If so, how many of the possible stereoisomers are formed in this synthesis?arrow_forwardEnamines normally react with methyl iodide to give two products: one arising from alkylation at nitrogen and the second arising from alkylation at carbon. For example, Heating the mixture of C-alkylation and N-alkylation products gives only the product from C-alkylation. Propose a mechanism for this isomerization.arrow_forward
