amide substituents have received less attention due, in part, to the lack of practical synthetic strategies. Here, we report the synthesis of α-hydrazino acids derived from 19 out of the 20 canonical proteinogenic amino acids and demonstrate their use in the solid-phase synthesis of N-amino peptide derivatives.
