A graduate student was studying enzymatic reductions of cyclohexanones when she encountered some interesting chemistry. When she used an enzyme and NADPH to reduce the following ketone, she was surprised to find that the product was optically active. She carefully repurified the product so that no enzyme, NADPH, or other contaminants were present. Still, the product was optically active. Does the product have any asymmetric carbon atoms or other stereocenters?
Propose a series of reactions that would convert the provided starting material into the given product. The synthesis will take more than one step. For each reaction you use, show the reagents you would use and the product of that step. In each step, your desired product should be formed as the major product. Assume chiral products are formed as racemic mixtures. Your reactions should give the correct diastereomer. In addition to the provided starting material, you may use any other organic compound as well as any reagents we have discussed.

The reaction occurs with Markovnikov regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called an enol. The enol immediately rearranges to a more stable ketone via tautomerization.
