Give a reasonable synthesis for
each of the following compounds from the indicated starting
materials. You may use any other organic or inorganic reagents you
wish unless otherwise indicated. The desired product for each
reaction you propose must be the one of the predominant products.
Give the reactants, conditions (where appropriate) and products of
each synthetic step. If equal mixtures are anticipated (i.e. ortho
/ para products) then indicate where separations are needed. NO

The two structures for the assignment are above and
the task is:
1. Perform a retrosynthetic analysis on the two target
molecules assigned to you. In each case the organic
starting material (what you have to work backwards toward) depends
upon the target. For the structure given above (structure on left),
the starting material is either malonic ester or acetoacetic ester
and any halide. For the structure given above (structure on right),
the starting material is any...

3. Aromatic or no? Label each of the following compounds as aromatic, non-aromatic, or anti- aromatic, and explain each answer briefly. 4. Design a multi-step synthesis for the following transformation. For EAS reactions, you may make a mixture of ortho and para products and then simply state "separate" to give you the desired isomer.
