5. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation of various kinds, and is the active ingredient in the over-the-counter drug called Aleve. It operates by inhibiting the enzyme cyclooxygenase (COX) similarly to the more common ibuprofen, but does so with a stronger binding affinity The following pathway shows one example of a multistep synthesis that has been used to access naproxen. a Provide the missing intermediates, reagents, or major organic product in each box...
The picture below is an example of how this assignment should be
done.
This experiment involves the synthesis of a target molecule using Grignard reagents. You must do the following: 1. Perform a retrosynthetic analysis on the target molecule. The organic starting material (what you have to work backwards toward) is provided. Draw a retrosythetic scheme; use the rightwards double arrow to show functional group transformations and disconnections. Provide synthons and synthetic equivalents for every disconnection made. 2. Propose the...
