Extra Credit (5 points) In our section on alcohols, we learned about reactions of alcohols with toluenesulfonyl chloride to make tosylates. Sulfonyl chlorides also react with amines and nitrogen heterocycles to make sulfonamides. See starting material 1 below for an example of a sulfonamide. While tosylates are good leaving groups, sulfonamides are not. In fact, sulfonamides often serve as protecting groups for amines and nitrogen heterocycles. However, deprotection of sulfonamides is often challenging. The following deprotection of an indole derivative...
