Abstract

Combinatorial chemistry has revolutionized the way potential new drugs are discovered. This simple experiment utilizes the Fischer esterification, a common reaction in second-semester organic laboratories, to demonstrate the fundamentals of combinatorial methods. These include simultaneous synthesis of numerous compounds, a selective assay for a desired activity, and an algorithm for identifying the active structure. Using a parallel synthesis combinatorial method, each student in a lab section prepares a different ester. The targeted activity (the characteristic odor of wintergreen) is easily detected by smell. The student's enjoyment of the lab is enhanced by the preparation of several other characteristic odors as well.
