Question

Take the following compound, benzoquinone, which is considered a 'readily available starting material' in this task. Devise a 7-step synthesis starting from benzoquinone (i.e. CREATE YOUR OWN TARGET MOLECULE). You may use any chemically reasonable reactions and any other reagents as necessary, however, there must be two or more carbon-carbon bond forming reactions included. Strictly follow the requirements stated below to complete this task:

1) Present the synthesis as a reaction scheme, giving all reagents and any special reaction conditions required. For EACH STEP, give mechanisms, NOTES and COMMENTS (especially if there may be selectivity issues that may arise).

2) Trivial procedures normally considered an integral part of a reaction step (e.g. the hydrolytic work-up of a Grignard reaction) DO NOT count as a separate step.

3) Circular or trivial schemes will not be well received. For example, all the carbon skeleton of the starting material should appear in the final product of the proposed scheme (this would not include the ethyl groups of an ethyl ester or diethyl acetal etc.)

4) Strictly take NOTES of the principles of selectivity, activation and protection.

5) DO NOT be too complex on devising the 7-step scheme as this may cause regio- or stereoselectivity problems. Keep the scheme well thought of and not too complicated.

NOTE: PLEASE EXPLAIN EACH STEP IN THE SYNTHESIS AS THIS IS CRUCIAL and NAME THE PRODUCTS IN THE 7-STEP SYNTHESIS
