If the starting compound in one example of these reactions is sterically hindered and doesn't react quickly enough with the aminopyridine catalyst, unwanted formation of N-acylureas will greatly decrease yield.
If the starting compound in one example of these reactions is sterically hindered and doesn't react quickly enough with the aminopyridine catalyst, unwanted formation of N-acylureas will greatly decrease yield. In another of these reactions, an anhydride intermediate is formed by reacting the starting compound with 2,4,6- trichlorobenzoyl chloride. DMAP catalyzes a reaction of this type in which DCC is the coupling reagent. Two types of these reactions are named for Yamaguchi and Steglich. A hydrolysis reverses this reaction in a saponification. The most famous type of this reaction refluxes an alcohol and a carboxylic acid to produce a compound with chemical group C-O-O-H. For 10 points, name this type of reaction, the most famous example of which is named for Emil Fischer.
