Maximizing the stereochemical diversity of spiro-ladder oligomers

We introduce all stereoisomers of a bis-amino acid building block derived from trans-4-hydroxy-L-proline. This small library of monomers allows arbitrary stereochemical configuration at any chiral center within our spiro-ladder oligomers. Three tetramer o
