**(left structure)****(right structure)** 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...
