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...

PREPARATION OF PHARMACEUTICALS - Fischer Esterification
Reactions
Q: Calculate the expected mass of both methyl salicylate and
aspirin assuming 100% yield.
EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
