The complete assignment of the 1H and 13C NMR spectra of eight thienyl-substituted chromenes was achieved by the concerted application of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradientselected correlation experiments.

✦ Synopsis
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.
