Swern oxidation

Explain an organic reaction to the general public to make it understandable even if it is a complicated topic. Which functional group are you targeting with your chosen reaction? Which functional group are you obtaining? Why is this reaction used in drug discovery? What is the mechanism (you should draw the mechanism with arrows and electrons) for your reaction? Please CLEARLY draw the molecule and mechanism on paper. What are the reagents used in the reaction such as solvents? What are the conditions of the reaction? Are there any side products formed during the reactions? If yes, how can you limit them?
