Design a multi-step synthesis of the target below, starting with benzene and cyclohexene. No additional carbon sources should be used for the carbons incorporated into the final product. Make sure to include all reagents/conditions and major organic products for each step in your synthesis. No mechanisms are needed.

Propose an efficient synthesis for the given transformation. OH This transformation can be performed with some reagent or combination of the reagents listed below. Give the necessary reagent(s) i the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer.

Propose a sequence of reactions to prepare the specified target compound from the indicated starting materials.  All of the carbon atoms in the target must originate in the specified starting materials.  Keeping this restriction in mind, you may use any other organic or inorganic reagents necessary to complete the synthesis. It is only necessary to show the overall transformations involved in your proposed synthesis.

Starting with benzene and using any other necessary reagents of your choice, design a synthesis the following compound. Note: some of these problems have more than one plausible answer.
