Herein, a method for the isomerization of the double bonds in tetrahydroxanthones is reported. Tetrahydroxanthones are readily available from salicylaldehydes and cycloalkenones and undergo isomerization upon treatment with AlCl3. The mechanism of the isomerization and follow-up chemistry of the products were investigated. Follow-up chemistry such as asymmetric Corey–Bakshi–Shibata (CBS) reduction
