title: Synthesis of a bis-amino acid that creates a sharp turn.
abstract: [reaction: see text] The synthesis of a new bis-amino acid 1 is presented. This monomer is designed to create a tightly curved structure when assembled into oligomers. The monomer is demonstrated to couple to the previously developed monomer 2 through pairs of amide bonds to create a strongly bent spiro-ladder oligomer. The structure of oligomer 3 was determined in aqueous solution using two-dimensional NMR.
