Cyclic trimers of chiral furan amino acids

Chiral furan amino acids were synthesized as novel peptide building, blocks. Cyclooligomerization of these monomers by a single-step process led to the selective formation of chiral C-3-symmetric cyclic trimers, which were studied for their structures and properties, like anion binding and antimicrobial activities. Key words: chiral furan amino acids, anion binding, synthetic, receptors, cyclic trimers, antimicrobial activities.
