Provide an efficient multistep synthesis for the conversion of the given starting material into the target molecule shown to the right. You must begin with the given starting organic compound. Each C that ends up in the target compound must come from the given starting organic compound. For each functional group transformation, give all necessary reagents, solvents, and catalysts; give a structural formula for each organic reactant and the major organic product(s). Show stereochemistry appropriately when necessary. If a mixture of products (for example a mixture of stereoisomers) must be present after a step, assume that you can separate the mixture and take the one needed product forward through the next step.
