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

Bis (amino acid) molecular scaffolds

The present invention provides molecular building blocks of rigid bis(amino acids). The molecular building blocks can be linked together through the formation of rigid diketopiperazine rings, to provide the desired three dimensional structure. Also provided is method of synthesizing macromolecules from the bis (amino acid) building blocks.
