title: 1H and 13 C spectral assignments of 7beta-(cinnamoyl-substituted)amino-3-acetoxymethyl-cephalosporins.
abstract: The (1)H and (13)C spectroscopic data for 7beta-(cinnamoyl-substituted)amino-3-acetoxymethyl-cephalosporins were fully assigned by a combination of one- and two-dimensional experiments. Substitution on the aromatic ring and on the double-bond alpha-position of the cinnamoyl moiety has little influence on the spectroscopic properties of the 7beta-aminocephalosporanic acid parent moiety.
