## Abstract Detailed assignments of ^1^H and ^13^C NMR spectral data for 13 β‐substituted cycloenones are reported. The assignments are based on 1D ^1^H and ^13^C NMR and on 2D shift‐correlated (^1^H,^13^C‐HMQC and HMBC), __J__‐resolved and COSY and double irradiation experiments. Copyright © 2005

Abstract
The ^1^H and ^13^C spectroscopic data for 7β‐(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 α‐position of the cinnamoyl moiety has little influence on the spectroscopic properties of the 7β‐aminocephalosporanic acid parent moiety.
