Conformationally constrained compounds which mimic the secondary structure of ß-strand regions of biologically active peptides and proteins are disclosed. Such ß-strand mimetic structures have utility over a wide range of fields, including use as diagnostic and therapeutic agents. Libraries containing the ß-strand mimetic structures of this invention are also disclosed as well as methods for screening the same to identify biologically active members.
Antibacterial activity is exhibited by 2-azetidinones having a 3-acylamino substituent and a 1-substituent of the formula ##STR1## (or a salt or ester thereof).

of peptide acetals via nucleophilic attack of a phenyl group on an endocyclic acyliminium ion 4 was explored as a route to novel amino acid derived heterocycles and peptidomimetic scaffolds. In the presence of protic acid, bridged structures such as 6 are formed readily from phenylalanine derivatives, but the fused-ring analogues 5 could not be obtained in good yield. In contrast, radical cyclization
