Concept Introduction:
>Alkylation of acetylene takes place in two steps.In the first step, the acetylene is treated with sodium amide, which converts it to its conjugate base. In step two, the acetylide ion reacts with an
Repeating the alkylation sequence of steps using a different alkyl halide converts the acetylene to its disubstituted derivative. The triple bond is internal in this derivative.
>Ozonolysis of
In ozonolysis, each of the triple bonded carbon atoms changes to the carboxyl carbon.
>In case of terminal alkynes, one of the products of ozonolysis is carbonic acid, which further dissociates into carbon dioxide and water.

- When a mixture of ketone 11 and \alpha, \beta - unsaturated carbonyl 12 are exposed to substoichiometric amounts of NaOMe, product B is obtained selectively. Subsequent treatment of B with excess NaOMe leads to the exclusive formation of tricyclic product 13. (1) Suggest a structure for B and provide a reason for its selective formation. (ii) Provide a reaction mechanism for the formation of 13, which accounts for its selective formation.arrow_forwardCompound EE, C5H10O gives a positive result (formation of silver mirror) when reacted with Tollen’s reagent. Reduction of EE with sodiumborohydride, NaBH4 followed by acidified water, H3O+ produces compound FF. Dehydration of compound FF uses concentrated sulphuric acid, H2SO4 at a temperature of 180°C produces compound GG. Compound FF also reacts with hot acidified potassium dichromate, K2Cr2O7 to produce 2-methylbutanoic acid, C4H9COOH. Esterification between 2-methylbutanoic acid and methanol, CH3OH produces compound HH. Draw the structural formula of compounds EE, FF, GG, and HH.arrow_forwardPropylene oxide is a chiral molecule. Hydrolysis of propylene oxide gives propylene glycol, another chiral molecule. A. Provide a mechanism for the acid-catalyzed hydrolysis of pure (R)-propylene oxide (treatment with H2SO4/H2O), showing the correct stereochemistry. B. Provide a mechanism for the treatment of pure (R)-propylene oxide with NaOH in water (base-catalyzed hydrolysis), showing the correct stereochemistry. C. Explain why acid-catalyzed hydrolysis of optically active propylene oxide gives a product with a rotation in the opposite direction from the product of the base catalyzed hydrolysis.arrow_forward
- 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_forwardFollowing is a retrosynthetic analysis for the synthesis of the herbicide (S)-Metolachlor from 2-ethyl-6-methylaniline, chloroacetic acid, acetone, and methanol. Show reagents and experimental conditions for the synthesis of Metolachlor from these four organic starting materials. Your synthesis will most likely give a racemic mixture. The chiral catalyst used by Novartis for reduction in Step 2 gives 80% enantiomeric excess of the S enantiomer.arrow_forwardFollowing is a retrosynthetic analysis for an intermediate in the industrial synthesis of vitamin A. (a) Addition of one mole of HCl to isoprene gives 4-chloro-2-methyl-2-butene as the major product. Propose a mechanism for this addition and account for its regioselectivity.

- Treatment of 1-aminoadamantane, C10H17N, with methyl 2,4-dibromobutanoate in the presence of a nonnucleophilic base, R3N, involves two successive SN2 reactions and gives compound A.

Propose a mechanism for each step in this transformation and account for the regioselectivity of HCl addition.arrow_forwardCembrene, C20H32, is a diterpenoid hydrocarbon isolated from pine resin. Cembrene has a UV absorption at 245 nm, but dihydrocembrene (C20H34), the product of hydrogenation with 1 equivalent of H2, has no UV absorption. On exhaustive hydrogenation, 4 equivalents of H2 react, and octahydrocembrene, C20H40, is produced. On ozonolysis of cembrene, followed by treatment of the ozonide with zinc, four carbonylcontaining products are obtained: Propose a structure for cembrene that is consistent with its formation from geranylgeranyl diphosphate.arrow_forward
- The base-promoted rearrangement of an -haloketone to a carboxylic acid, known as the Favorskii rearrangement, is illustrated by the conversion of 2-chlorocyclohexanone to cyclopentanecarboxylic acid. It is proposed that NaOH first converts the a-haloketone to the substituted cyclopropanone shown in brackets and then to the sodium salt of cyclopentanecarboxylic acid. (a) Propose a mechanism for base-promoted conversion of 2-chlorocyclohexanone to the proposed intermediate. (b) Propose a mechanism for base-promoted conversion of the proposed intermediate to sodium cyclopentanecarboxylate.arrow_forward-Ocimene is a pleasant-smelling hydrocarbon found in the leaves of certain herbs. It has the molecular formula C10H16 and a UV absorption maximum at 232 nm. On hydrogenation with a palladium catalyst, 2,6-dimethyloctane is obtained.
