substitution of 2-indolylmethanols with nucleophiles such as cyclic enaminone and cyclic anhydride has been established in the presence of Brønsted acid, which efficiently afforded C3-functionalized indole derivatives with structural diversity in high yield and regiospecificity (40 examples, up to 99% yield). Using this approach, the reactivity of the C3-position of the indole was switched from nucleophilic to
