Peculiarity of methoxy group-substituted phenylhydrazones in Fischer indole synthesis
We found that the Fischer indole synthesis of ethyl pyruvate 2-methoxyphenylhydrazone (5) with HCl/EtOH gave an abnormal product, ethyl 6-chloroindole-2-carboxylate (7), as the main product, with a smaller amount of ethyl 7-methoxyindole-2-carboxylate (6) as the normal product. This abnormal reactio...
