✦ Synopsis

1H and 13C NMR spectral data for several pyridoÍ2,3-b Ëpyrazines and pyridoÍ2,3-b Ëpyrazine-N -oxides are reported. The chemical shift assignments were based on 1D-NOE, gradient HSQC and gradient HMQC experiments for some model compounds. 1997 < by John Wiley & Sons, Ltd.

## Abstract In an attempt to develop potent antitumor agents, a series of novel 2‐hydrazonylpyrido[2,3‐__b__]pyrazin‐3(4__H__)‐one derivatives were designed and synthesized. All the prepared compounds were screened for their cytotoxic activities against A549, MDA‐MB‐231 and HT‐29 cell lines __in vi

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.
