Abstract
^1^H and ^13^C NMR spectral data for seven 2‐oxo‐2__H__‐1‐benzopyran‐3‐carboxamide and two 2‐oxo‐2__H__‐1‐benzopyran‐3‐amide derivatives are reported. The chemical shift assignments were based on two‐dimensional experiments. Copyright © 2001 John Wiley & Sons, Ltd.

The 1H and 13C NMR resonances of four 3H-naphtho[2,1-b]pyrans were completely and unambiguously assigned by a combination of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient-selected correlation experiments.
