Describe a synthesis for each of the following compounds, using the given starting material and any necessary reagents:
b. 
Verified step by step guidance1
Identify the target compound and analyze its functional groups and structure. Determine the transformations required to convert the given starting material into the target compound.
Examine the starting material and identify its functional groups and structure. Consider how these can be modified to introduce the functional groups or structural features present in the target compound.
Plan the synthesis by selecting appropriate reagents and reaction conditions for each transformation. For example, if the target compound requires the introduction of a hydroxyl group, consider reactions such as hydroboration-oxidation or epoxidation followed by ring opening.
Sequence the reactions logically, ensuring that each step is compatible with the functional groups present and does not interfere with subsequent steps. Protecting groups may be used if necessary to prevent unwanted side reactions.
Write out the complete synthetic pathway, including all reagents, reaction conditions, and intermediates. Verify that the proposed synthesis is feasible and efficient, and that it leads to the desired target compound.

Functional Groups
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. Identifying functional groups in both starting materials and target compounds is vital for predicting reactivity and determining the necessary transformations during synthesis. Knowledge of how different functional groups interact is key to planning a successful synthetic route.
