6-methoxytetralins may be smoothly transformed into 5-methoxytetralins through the action of zirconiumtetrachloride. The rearrangement occurs at ambienttemperature in chloroform and proceeds via fragmentation of the carbon - carbon bond para to the methoxy substituent followed by an intramolecular Friedel-Crafts alkylation

alkenes, which enables the synthesis of chromans, quinolinones, and tetrahydronaphthalenes that are precisely deuterated at the benzylic position. We also demonstrate the ability to place one deuterium atom at the homobenzylic site of these scaffolds with high regioselectivity by swapping transfer reagents for their isotopic analogs. Furthermore, examples of chemoselective transfer hydrogenation and transfer
