Ugi 4-CR Synthesis of ?- and ?-Lactams providing new access to diverse enzyme interactions, a PDB analysis.


ABSTRACT: A three step synthesis of N-unsubstituted tetrazolo ?- and ?-lactams involving a key Ugi-4CR is presented. The compounds, otherwise difficult to access, are conveniently synthesized in overall good yields by our route. PDB analysis of the N-unsubstituted ?- and ?-lactam fragment reveals a strongly tri-directional hydrogen bond donor acceptor interaction with the amino acids of the binding sites.
