A simple AlCl 3 ‐catalyzed condensation/cyclization cascade process between aldehydes and sulfonamide is reported, in which two new bonds and one five‐membered ring are simultaneously formed with water as the byproduct. This method provides a rapid access to indenamine and 9‐aminofluorene derivatives. Additionally, these products can be transformed into corresponding indanones and fluorenones under the developed conditions.
