The preparation of the angular and linear isomers of benzo‐fused 1,4‐dimethyl‐2(1 H )‐quinolinones 3a–5a and their spectral data including 13 C‐nmr data are reported. Structural difference among 3a–5a is confirmed from the proximity effect in 1 H‐ and 13 C‐nmr data and from the uv spectral pattern.
