One class of reagents used to synthesize this functional group can interconvert between uronium and guanidinium forms.
One class of reagents used to synthesize this functional group can interconvert between uronium and guanidinium forms. EDC, HATU, and hydroxy-benzo-tri-azole are used to synthesize this functional group via a coupling reaction. One variant of this functional group is characterized by a methyl and a methoxy substituent, which allows them to selectively form ketones via nucleophilic substitution by organometallic reagents due to chelation with the methoxy group. The bromination of this functional group results in its decomposition into an amine via an isocyanate intermediate in the Hofmann rearrangement. This functional group is formed via a condensation reaction between a carboxylic acid and an amine. For 10 points, name this functional group which is found between amino acids in peptide bonds, and consists of a nitrogen atom adjacent to a carbonyl.
