4-Amino-3-(aminomethyl)benzoic acid (1) (AmAbz) is a novel unnatural amino acid with promise in applications as a building block for the synthesis of peptidomimetics and as a scaffold for combinatorial chemistry. It was efficiently synthesized in three steps (63% overall yield) from 4-aminobenzoic a
