(13)C NMR spectroscopic data for 25 cephalosporin derivatives were assigned by combination of one- and two-dimensional experiments. The effect of the substitution at C-3, C-7 and C-4 acid group positions on the chemical shifts of the cephem nucleus is discussed.

Abstract
(13)C NMR spectroscopic data for 25 cephalosporin derivatives were assigned by combination of one- and two-dimensional experiments. The effect of the substitution at C-3, C-7 and C-4 acid group positions on the chemical shifts of the cephem nucleus is discussed.File in questo prodotto:
