## Abstract In Simonis reaction with ethyl acetoacetate naphthalene‐2,6‐diol gives 8‐hydroxy‐3‐methyl‐1H‐naphtho[2,1‐b]‐pyran‐1‐one and naphthalene‐2,7‐diol gives the related 9‐hydroxy isomer. In Pechman reactions, the former diol yields a coumarin, 8‐hydroxy‐1‐methyl‐3H‐naphtho[2,1‐b]‐pyran‐3‐one,
