We introduce all stereoisomers of a bis-amino acid building block derived fromtrans-4-hydroxy-l-proline. This small library of monomers allows arbitrary stereochemical configuration at any chiral center within our spiro-ladder oligomers. Three tetramer oligomers containing several combinations of the monomers1−4were synthesized; we explored the effect of monomer sequence on scaffold conformation by NMR.
