Concept explainers
(a)
Interpretation:
Synthesis of the given compound beginning with pentan-2-one is to be suggested.
Concept introduction:
The carbon–carbon bond-forming reaction results in heteroatoms having a specific relative positioning along the carbon backbone. If the heteroatoms in a target have 1, 2-, 1, 3-, 1, 4-, or 1, 5- relative positioning, and the synthesis calls for a carbon–carbon bond-forming reaction, then consider using a corresponding reaction from Table 19-1. In a retrosynthetic analysis, therefore, apply a transform that takes our target molecule back to reactants. Disconnect the appropriate C-C bond to take back to the reactants, and from retrosynthetic analysis, we can draw the synthesis of the target molecule.

The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forward
