Abstract Several ketenimines bearing ester groups were prepared and their thermal reactions gave 2‐alkoxy‐3‐substituted‐4‐quinolinols VIa‐e via presumed iminoketene intermediates. Subsequent oxidation of 2‐alkoxy‐3‐(3‐methylbut‐2‐enyl)‐4‐quinolinols VIc and VId provided pyranoquinolines VIIIa and VIIIb.
