A synthetic procedure was developed for the preparation of sterically hindered di- and trisubstituted catechols and o-quinones by the reaction of catechol with isopropanol. Compared to sterically more hindered analogs, o-quinones bearing isopropyl substituents exhibit a higher reactivity toward the formation of oxanthrenequinone derivatives.
