Article abstract of DOI:10.1021/jm00240a023

7 Aminocephalosporanic acid tert butyl ester reacts quantitatively at -20°C with iminium chlorides to give amidino derivatives. Removal of the tert butyl protecting group with trifluoroacetic acid and treatment with 1 equiv of triethylamine yield the corresponding zwitterions. These compounds were less active than their penicillin analogs.
