Pre-lab Questions:
Importance A one-step preparation of aspirin from its precursor, salicylic acid, via an ester formation illustrates one of synthetic organic chemistry's most important uses, making the drugs that treat all types of illnesses. OH HOOH Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the ancient Greeks as a treatment for pain...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
