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...
