A short and scalable process for the preparation of multi-gram quantities of orthogonally protected bis(aminomethyl)malonic acid in good yield from readily available starting material is described. These orthogonally protected amino acids are important building blocks to make peptides based drugs, glycoconjugates, and in the total synthesis of peptide natural products. The newly developed route has only six steps with an overall yield of 27%, which involves nucleophilic attack of a malonate on an imide as one of the key steps.
