Methoxy-substituted centrohexaindanes through the fenestrane route.
Tetrahydroxyfenestrindane undergoes HPF6-catalyzed condensation with anisole, 2-methylanisole and the three dimethoxybenzenes to furnish several centrohexaindanes bearing oxyfunctionalization at the opposite ends of one of the three [2,2']-spirobiindane axes.
متن کاملPeculiarity 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 reaction was the result of a cyclization on the side with the substituent (methoxy group) of a benzene r...
