Because sodium cyanoborohydride is unreactive toward carbonyl groups, it can be used to form these compounds in a "reductive" reaction.
DCCI and BOP-Cl are common reagents in reactions involving carboxylic acids and these compounds. A common protective group for these compounds is Cbz, or a benzyloxycarbonyl group. Because sodium cyanoborohydride is unreactive toward carbonyl groups, it can be used to form these compounds in a "reductive" reaction. Secondary ones can be formed in a variant of hydroboration that takes place between trisubstituted boranes and alkyl or aryl azides. They can be formed from carboxylic acids in Hoffman rearrangement. These compounds can catalyze Knoevenagel condensations, as can a buffer solution of these compounds and their conjugate acids. These compounds are formed from phthalamide in the Gabriel synthesis. For 10 points, name these compounds that contain an -NH2 group.
