A Lewis-acid-promoted approach to the synthesis of highly functionalized dihydrobenzofuranderivatives was developed. A diverse range of functional groups are tolerated in this type of reaction. The reaction mechanism investigation indicates that the highly reactive phenyl cation intermediate is probably involved in this process. The chirality of substrate is retained under the reaction conditions

Rings, rings, rings: A Friedel–Crafts intramolecular arylation for the synthesis of polycyclicaromatichydrocarbonsfromaryltriazenes has been achieved. Polycyclicaromatic compounds consisting of five‐, six‐, and seven‐membered rings can be prepared using this method.
