Structural variants of the acylamino side chain of penicillins have been tested as substrates for Deacetoxy/Deacetyl Cephalosporin C Synthetase from CO 728. A six carbon chain terminating in a carboxyl group was found to permit efficient ring expansion to cephems, with the exception of δ-(-α-aminoadipoyl).1
