Reaction of an alcohol with tosyl chloride forms a (*) "sulfonate" one of these compounds.
Hydrolysis of a Pinner salt generates these compounds, which can also be synthesized by adding 2,4,6-trichlorobenzoyl chloride and DMAP to a carboxylic acid. This functional group is found in the amine protecting group t-BOC. They're not peptides, but DCC can be used as a coupling agent alongside DMAP to form these compounds. Reaction of an alcohol with tosyl chloride forms a (*) "sulfonate" one of these compounds. Under base catalysis, two of these compounds can react to form one compound containing this functional group beta to a ketone. The most common synthesis of these compounds is done via an acid-catalyzed reflux of an alcohol with a carboxylic acid. For 10 points, the Claisen condensation and Fischer reaction synthesize what compounds named for their fruity smells?
