Concept explainers
Interpretation:
The retrosynthesis analysis and the actual synthesis are to be written for the preparation of each target molecule from the given starting molecule.
Concept introduction:
>The retrosynthesis is a reaction that involves
on acid catalyzed dehydration, an alcohol gives the corresponding more substituted alkene as the major product.
>The alkene, on reaction with halogen in water, undergoes addition of halogen and hydroxyl group across the double bond in a way that the halogen atom is bonded to the less substituted double bonded carbon atom and hydroxyl group is bonded to the more substituted double bonded carbon atom.
>Alkenes react with hydrogen halide and yield haloalkane.
>Alkenes, on hydration, form more substituted alcohol.
>Alkenes, on hydroboration-oxidation, form less substituted alcohol.
>Alkenes, in presence of peroxy acid, undergo
In presence of a strong base,

- Beginning with phenylacetylene, outline a method to synthesize the following secondary alcohol, necessitating a sequence of synthetic stages. You are permitted to employ any reactants from any part of your organic chemistry coursework; however, if any reactant contributes additional carbon atoms, it must initially be in the form of an alcohol (for instance, if you intend to use propyl bromide, you must first derive it from propanol before proceeding).arrow_forwardAcetal formation is a characteristic reaction of aldehydes and ketones, but not of carboxylic acids. Use retrosynthetic analysis to show how you could use a cyclic acetal protecting group in the following synthesis, then write equations for the procedure showing the necessary reagents.arrow_forwardWittig reactions with the following -chloroethers can be used for the synthesis of aldehydes and ketones. (a) Draw the structure of the triphenylphosphonium salt and Wittig reagent formed from each chloroether. (b) Draw the structural formula of the product formed by treating each Wittig reagent with cyclopentanone. Note that the functional group is an enol ether or, alternatively, a vinyl ether.
