which the desired acid‐catalyzed reaction could be promoted and, at the same time, a side reaction that also needs assistance of acid, the electrophilic reaction of indole with the co‐existing keto carbonyl group, does not occur. Some acid‐catalyzed reactions, such as the ring‐opening reaction of 2‐alkoxy‐3,4‐dihydropyran with indole, and transesterification of β‐ketoester with an alcohol that contains
