AN ARTIFICIAL RECEPTOR FOR THE INTERMOLECULAR AND ENANTIOSELECTIVE FORMATION OF PEPTIDE SHEETS

Peptide strands coupled at the C terminus to bis[p(aminomethyl)phenyl] ether allow in CHCl3 solution association of lipophilic N-protected p eptides with hydrogen bonds in the mode of antiparallel beta-sheets; t he enantioselectivity observed with a phenylalanine derivative is char acterized by a binding constant ratio of around 15.
